Symposium on Space Terahertz Technology
, 2003
"... public and private sectors. Recent advances in theory, fabrication, and analytical tools permit for the first time the realization of devices, components, and systems that were only imagined just a short time ago. Much of this accelerated growth can be traced directly to the instrument requirements ..."

in the millimeter-wave (mmW) and terahertz (THz) bands due to the unique features they provide for various applications. For example, the mmW is not significantly affected by the atmospheric constraints and it can penetrate through clothing and other dielectric materials. Therefore, it is suitable for a vast range
Architectures and System Design for Digitally-Enhanced Antenna Arrays
, 2013
"... Digital techniques have had longstanding use in both the operational control and signal processing efforts associated with phased array antennas. Fundamentally, these techniques have served to provide additional levels of convenience and performance over the fully analog counterparts, without specif ..."

. Emergent trends in millimeter wave and low-terahertz circuit technology are enabling the prospect of physically small, yet electrically large antenna arrays for a host of exciting new communication, radar, and imaging applications. Still, the high cost of phased arrays remains a significant bottleneck
Review of Terahertz Tomography Techniques
"... Abstract Terahertz and millimeter waves penetrate various dielectric materials, including plastics, ceramics, crystals, and concrete, allowing terahertz transmission and reflection images to be considered as a new imaging tool complementary to X-Ray or Infrared. Terahertz imaging is a well-establish ..."

Towards Room-Temperature Terahertz
, 2015
"... Terahertz Quantum Cascade Lasers (THz QCLs) are arguably the most promising technology today for the compact, efficient generation of THz radiation. Their main limitation is that they require cryogenic cooling, which dominates their ownership cost. Therefore, achieving room-temperature operation is ..."

Fundamentals of Terrestrial Millimeter-Wave and THz Remote Sensing
- International Journal of High Speed Electronics and Systems
, 2003
"... Having long been the realm of molecular chemistry, astronomy, and plasma diagnostics, the upper millimeter-wave band (~100 to 300 GHz) and the THz region above it have recently become the subject of heightened activity in the engineering community because of exciting new technology (e.g., sub-picose ..."

Terahertz transport dynamics of graphene charge carriers
, 2013
"... The electronic transport dynamics of graphene charge carriers at femtosecond (10-15 s) to picosecond ( 1210 s ) time scales are investigated using terahertz ( 1210 Hz) time-domain spectroscopy (THz-TDS). The technique uses sub-picosecond pulses of electromagnetic radiation to gauge the electrodynam ..."
