Towards large area THz electromagnetic metamaterials (Paper 
Presentation)
Paper 7029-12 of Conference 7029
Authors(s): Herbert O. Moser, National Univ. of Singapore (Singapore)
Date: Sunday, 10 August 2008
Up to date, metamaterials have been mostly produced by primary pattern 
generation via e-beam or laser which is time-consuming and may yield only 
limited useful areas. Particularly, e-beam writing may only cover some 100×100 
μm2. However, many applications require larger quantities of good quality 
materials. Since 2002, SSLS has been using its X-ray-lithography-based LIGA 
process to micro/nanomanufacture a variety of high-aspect-ratio metamaterials 
structures. Split-ring designs have led to resonance frequencies from 1 - 216 
THz. Meanwhile, stringlike structures have also been included. Latest progress 
in the manufacturing and characterization of 1 cm2 quasi-3D metamaterials 
structures will be described.
Surface-plasmon-polariton-enhanced reflected THz-field (Paper 
Presentation)
Paper 7065-3 of Conference 7065
Authors(s): Dan-Hong Huang, Air Force Research Lab.; Godfrey A. Gumbs, Hunter 
College/CUNY; Paul M. Alsing, David A. Cardimona, Air Force Research Lab.
Date: Monday, 11 August 2008
The present work predicts the large enhancements at the band edges of a coupled 
Bloch-surface-plasmon-polariton band in the spectrum of the reflected far 
electromagnetic field due to anti-crossing gaps induced by the strong coupling 
between the continuous surface-plasmonpolariton mode and the discrete Bloch-like 
modes. The existence of these Bloch-like modes is a direct consequence of the 
nonlocal mixing of specular and diffraction modes of the reflected 
electromagnetic field by free-electron induced optical polarization and the 
interference of a pair of surface optical-polarization waves with opposite Bragg 
order numbers in the presence of a grating.
THz generation by X(3) media (Poster Presentation)
Paper 7056-48 of Conference 7056
Authors(s): Shizhuo Yin, Meng-Ku Chen, Peng Li, The Pennsylvania State Univ.
Date: Tuesday, 12 August 2008
In this paper, we review the THz generation in X(3) media via the third order 
nonlinear effects. For example, THz wave has been successfuly generated by the 
air plasma via the third order nonlinear effects by several groups around the 
world. Besides the air plasma in the free space form, the air plasma in a 
confined structure (e.g., metal waveguides, photonic crystal waveguides) and the 
possibility of generating THz wave in other types of isotropic media (e.g., 
glasses) are also investigated.
Plasmon mediated InGaAs/InP tunable far-IR detector (Paper 
Presentation)
Paper 7082-8 of Conference 7082
Authors(s): Walter R. Buchwald, Air Force Research Lab.; Himanshu Saxena, Robert 
E. Peale, Univ. of Central Florida
Date: Monday, 11 August 2008
This work presents an experimental investigation of a THz detector based on 
plasmon excitation in the two dimensional electron gas of a high electron 
mobility transistor. This device, fabricated from the InGaAs/InP material 
system, relies on e-beam lithography to fabricate a gate in the form of a 
grating with sub-micron period. Sensitivity of the device conductance to 
incident THz fields is reported. Direct absorption of THz radiation, temperature 
effects, and the effects of source to drain current on system performance are 
also investigated. It is expected that this class of device will find use in 
spaceborne remote sensing applications.

Future space borne or airborne heterodyne receivers will target frequency range 
of 2-6 THz, which holds crucial information on astronomical objects as well as 
on chemical composition of Earth’s atmosphere. Here we highlight the progress on 
heterodyne receivers above 2 THz. This includes our latest result i.e. 2100 K 
double side band receiver noise temperature at 3.5 THz using a distributed 
feedback (DFB) QCL as LO and an HEB mixer integrated with spiral antenna. We 
also discuss suitability of such a QCL as an LO in a real space instrument in 
terms of beam pattern, power consumption and stability.
Terahertz conductivity measurements in films of semiconductor and 
metallic single walled carbon nanotubes. (Paper Presentation)
Paper 7034-21 of Conference 7034
Authors(s): Matthew C. Beard, Michael J. Heben, Jeffery Blackburn, National 
Renewable Energy Lab.
Date: Tuesday, 12 August 2008
We report the frequency-dependent complex conductivity in the far-infrared for a 
series of single walled carbon nanotube (SWCNT) films where the ratio of 
metallic to semiconductor tube types has been systematically varied. We studied 
films of 6.2, 23.5, 29.5, 57.9, 93.1, and 97.8% metallic tube content. In 
addition we explored the effect on the THz conductivity when films are 
subsequently p-doped by treating with thionel chloride. We find that the real 
part of the conductivity increases with increasing frequency and the imaginary 
part is negative. This phenomenon is characteristic of materials that have a 
suppressed long range transport due to disorder or materials that exhibit 
stochastic transport. We analyze the results by using a Drude-Smith conductivity 
model at low frequencies and a lorenzitian oscillator at higher frequencies. We 
find that extracted dc conductivity from the ac (THZ) measurements compare 
favorably to a four-point-probe measurement.
Optical studies of plasmonic metamaterials (Paper Presentation)
Paper 7033-49 of Conference 7033
Authors(s): Valy Z. Vardeny, The Univ. of Utah
Date: Wednesday, 13 August 2008
Extraordinary optical transmission (EOT) through periodic and aperiodic arrays 
of subwavelength apertures is an example of metamaterial media. The 
subwavelength nature of the active surface plasmon polariton (SPP) excitations, 
along with strong field localization in these structures open up novel 
applications in bio-sensing, guided-wave devices and quantum optics. Our work 
has been primarily focused on the fundamental investigation and development of 
two-dimensional (2D) plasmonic metamaterials that are active in the visible, 
infrared and terahertz (THz) frequencies. Using pump-probe spectroscopy we 
investigated the transient response of photoexcited SPP excitations. Also using 
THz time-domain spectroscopy we measured the transmission properties of periodic 
and aperiodic aperture arrays.
Frontside-illuminated quantum well photodetector for far-infrared 
range (Paper Presentation)
Paper 7055B-21 of Conference 7055B
Authors(s): Mikhail A. Patrashin, Iwao Hosako, National Institute of Information 
and Communications Technology (Japan)
Date: Monday, 11 August 2008
We have demonstrated the operation of a frontside-illuminated GaAs/AlGaAs 
quantum well photodetector based on intersubband absorption in a quantum well (QW) 
with a targeted peak frequency of 3 THz. A multiple quantum well structure 
consists of 20 periods of 18 nm QWs interleaved by 80 nm barriers with an Al 
alloy content of 2%. We measured the following performance characteristics: dark 
current, responsivity, and spectral response. We looked also at possible designs 
to optimize the device’s performance.
Frequency dependence of the observed phase transition in 
nanostructured and doped VO2 thin films (Paper Presentation)
Paper 7041-18 of Conference 7041
Authors(s): Geoffrey B. Smith, Angus R. Gentle, Univ. of Technology/Sydney 
(Australia)
Date: Thursday, 14 August 2008
The nature of the phase transition in doped and nano-VO2 is shown to depend on 
the frequency at which it is observed. A transient correlated insulator is seen 
above Tc at frequencies under THz, while it appears metallic and uncorrelated at 
optical frequencies.
Trapping light without double negative index metamaterials for 
all frequencies (Paper Presentation)
Paper 7029-19 of Conference 7029
Authors(s): Wen-Tao Lu, Northeastern Univ.
Date: Monday, 11 August 2008
Recently, Tsakmakidis et al (Nature 450, 397 (2007)) proposed to use double 
negative index waveguide to trap light. In this talk, I propose different 
schemes to trap light in planar and cylindrical waveguide structures without the 
use of double negative index metamaterials. For frequencies ranged from 
microwaves, THz waves, and up to the visibles, different feasible realizations 
are provided and verified by numerical simulations. Our experimental results on 
trapping and slow light will also be discussed.
Surface plasmon localization for the optical control of field 
emission (Paper Presentation)
Paper 7037-26 of Conference 7037
Authors(s): Pierrick Guiset, Sylvain Combrie, Mathieu Carras, Alfredo De Rossi, 
Jean-Philippe P. Schnell, Pierre Legagneux, Thales Research & Technology 
(France)
Date: Tuesday, 12 August 2008
We present the first steps for the validation of an optically driven field 
emission cathode. This approach relies on the interaction of surface plasmons 
with vertically aligned multi-wall carbon nanotubes or metallic nanowires 
arrays. The objective is to modulate the field emission current by using the 
optical component at the field emitter apex through antenna coupling. Thanks to 
metallic surface cavities, surface plasmons will be generated and localized in 
the vicinity of nanoemitters to improve interaction efficiency. First 
simulations and experimental measurements will be presented jointly with 
perspectives for the wideband modulation of electronic beams till THz.
Terahertz wave propergation in structured metals (Paper

Date: Tuesday, 12 August 2008
Electromagnetic wave propagation in structured metals has attracted strong 
attention in wide wavelength regions from microwave to visible. We have 
investigated transmission properties of metal hole arrays in the terahertz 
region by using the terahertz time-domain spectroscopy (THz-TDS). We have found 
variety of transmission properties depending on the periodic structure of 
metals, i. e. extraordinary transmission, large polarization conversion, and 
large optical activity, etc. Some of the properties are explained by the surface 
plasmon-polariton and the local structure of holes.
Theoretical studies of defect states in GaSe and GaTe (Paper 
Presentation)
Paper 7079-26 of Conference 7079
Authors(s): Zsolt Rak, S. D. Mahanti, Michigan State Univ.; Krishna C. Mandal, 
EIC Labs., Inc.; Nils C. Fernelius, Air Force Research Lab.
Date: Tuesday, 12 August 2008
GaSe and GaTe are promising materials for radiation detectors and various opto-electronic 
devices including time-domain terahertz spectroscopy (TDTS), broadband tunable 
terahertz (THz) sources and detectors. In all these applications charge carrier 
creation and transport play crucial roles. Electrical, optical and transport 
properties of semiconductors are strongly affected by defects. In order to 
understand the nature of defect states in these semiconductors we have carried 
out ab initio studies using density functional theory and supercell model. 
Theoretical binding energy values for a series of defects in GaSe and GaTe are 
calculated and found to be in good agreement with the experimental result.
From nano to meta: plasmonic waveguides and their 
characterization in different parts of the spectrum (Paper Presentation)
Paper 7032-55 of Conference 7032
Authors(s): Stefan A. Maier, Imperial College (United Kingdom)
Date: Wednesday, 13 August 2008
This talk will present both design principles for plasmonic waveguides offering 
sub-wavelength scale mode confinement working in different parts of the 
spectrum, and important techniques for their experimental characterization. 
Examples will be drawn from plasmon waveguides working at visible frequencies, 
where sub-wavelength energy localization is achieved via intrinsic effects. At 
lower frequencies, a metamaterial approach is needed to engineer spoof surface 
plasmon polaritons modes with effective plasma frequencies controlled by the 
surface geometry alone. Numerical results as well as experimental demonstrations 
of waveguides operating in at visible and at THz frequencies will be discussed, 
and their properties assessed.
Ultrafast local investigations of plasmonic structures (Paper 
Presentation)
Paper 7032-59 of Conference 7032
Authors(s): Laurens Kuipers, FOM Institute for Atomic and Molecular Physics 
(Netherlands)
Date: Wednesday, 13 August 2008
Both plasmonic and periodic structures can exert a huge control over 
electromagnetic waves at the nanoscale. The result may be slow light in photonic 
crystal waveguides or huge field enhancements near metal nanostructures. With 
plasmonic crystals we gain the best of both worlds. Visualization of the 
propagation with subwavelength resolution allows the optical properties to be 
unravelled in detail. With a time-resolved near-field microscope we have tracked 
plasmonic wavepackets (duration 100 fs) as they propagate. We show that plasmons 
in periodic structures obey Bloch's theorem. Moreover, we can slow the 
wavepackets down for their entire bandwidth (~4 THz).
Terahertz plasmonic energy concentration (Paper Presentation)
Paper 7029-22 of Conference 7029
Authors(s): Mark I. Stockman, Maxim Durach, Anastasia Rusina, Georgia State 
Univ.
Date: Monday, 11 August 2008
We present theory of subwavelength terahertz spoofed plasmonics. We propose an 
approach to highly efficient concentration of the terahertz oscillation energy 
on a deep subwavelength scale using metamaterials structures. Efficient 
metal-dielectric structures structures are presented that allow for 
subwavelength focusing of terahertz waves to ~0.01 of the vacuum wavelength. 
Wide range of applications are possible and discussed.

Authors(s): Taiichi Otsuji, Tohoku Univ. (Japan)
Date: Wednesday, 13 August 2008
[Invited] “Metamaterial” is one of the emerging science and engineering regions 
where new paradigm of manipulating electromagnetic waves from microwaves to 
beyond optical waves in various extraordinary ways are just now being born. This 
presentation reviews recent advances in terahertz electromagnetic metamaterials. 
In particular, the topics will be focused on plasmonic metamaterials where 
material- and structure-dependent highly dispersive systems are configured in 
submicron-to-nanometer scaled artificial dimensions to perform emission, 
detection, and moreover higher functional signal processing like intensity 
modulation as well as frequency multiplication in an exploring terahertz 
frequency region.

We study the dielectric constant dependent diffraction phenomena of single slit 
aperture, both theoretically and experimentally. We experimentally simulate the 
perfect metal and a real metal cases by investigating sub-wavelength diffraction 
by a single slit, both in nano-optical and in terahertz regimes keeping the 
slit-width/wavelength ratio approximately the same for both of frequency 
regimes. The wave-front in optical regime separates itself into forward 
propagating beam and surface-bound 90-degree diffracted wave, i.e., surface 
plasmon polaritons; while separation of modes is not observed in terahertz 
regime.

    Terahertz Spectroscopy: Principles and Applications (Optical 
    Science and Engineering) ~ Susan L. Dexheimer The development 
    of new sources and methods in the terahertz spectral range has generated 
    intense interest in terahertz spectroscopy and its application in an array 
    of fields. Presenting state-of-the-art terahertz spectroscopic techniques, 
    Terahertz Spectroscopy: Principles and Applications focuses on time-domain 
    methods based on femtosecond laser sources and important recent applications 
    in physics, materials science, chemistry, and biomedicine.   | 
  
Principles of Terahertz Science and Technology (Lecture Notes in Physics) ~ Yun-Shik Lee Principles of Terahertz 
    Science and Technology aims to elucidate the fundamentals of THz technology 
    and science for potential new users. It surveys major techniques of 
    generating, detecting, and manipulating THz waves and also discusses a 
    number of essential processes where THz waves interact with physical, 
    chemical, and biological systems. This book serves as an introduction to THz 
    technology for new researchers in various fields.  |

Terahertz Science And Technology For Military And Security Applications (Selected Topics in Electronics and Systems) ~ Dwight L. Woolard The inherent advantages and potential payoffs of the 
    terahertz (THz) regime for military and security applications serve as an 
    important driver for interest in new THz-related science and technology. In 
    particular, the very rapid growth in more recent years is arguably most 
    closely linked to the potential payoffs of THz sensing and imaging 
    (THz-S&I).  |

| Terahertz Optoelectronics ~ Sakai, Kiyomi
    
     The book presents recent and important developments in the field of terahertz radiation with a particular focus on pulsed terahertz radiation. Situated in the gap between electronics and optics, the terahertz frequency range of the electro-magnetic spectrum has long been neglected by scientists and engineers due to a lack of efficient and affordable terahertz sources and detectors. The advent of femtosecond lasers in the 1980s and photoconductive switches in 1984 have made the terahertz gap accessible, while at the same time advances in electronics and optics have made it narrower. Research activities in terahertz frequencies have risen dramatically since that time, funding has increased by a factor of 100 in the last decade. The reviews by leading experts are of interest to researchers and engineers as well as advanced students.  |

| Intense Terahertz Excitation of Semiconductors ~ S. G. 
    Ganichev Product DescriptionIntense Terahertz Excitation of 
    Semiconductors presents the first comprehensive treatment of high-power 
    terahertz applications to semiconductors and low-dimensional semiconductor 
    structures. Terahertz properties of semiconductors are in the center of 
    scientific activities because of the need of high-speed electronics. This 
    research monograph bridges the gap between microwave physics and photonics. 
    It focuses on a core topic of semiconductor physics providing a full 
    description of the state of the art of the field.   |

Terahertz Frequency Detection and Identification of Materials and Objects ~ R.E. Miles Terahertz frequency sensing has 
    a unique part to play in the detection and identification of materials and 
    objects. This frequency range, corresponding to a wavelength of around 0.1 
    mm, can be used to identify materials from their molecular spectra and to 
    produce images of concealed objects. Terahertz spectra of drugs of abuse and 
    explosives presented by a number of the contributing authors show that the 
    presence of these materials can be detected in envelopes, packages and 
    through clothing.  |
