Terahertz, RF, Millimeter, and Sub-Millimeter-Wave Technology and Applications VI (OE106)

Conference Chairs: Laurence P. Sadwick, InnoSys, Inc. (USA); Créidhe M. O’Sullivan, National Univ. of Ireland, Maynooth (Ireland)

Program Committee: Antao Chen, Univ. of Washington (USA); Robert H. Giles, Univ. of Massachusetts Lowell (USA); R. Jennifer Hwu, InnoSys, Inc. (USA); Anthony Murphy, National Univ. of Ireland, Maynooth (Ireland); Michael C. Wanke, Sandia National Labs. (USA); Tianxin Yang, Tianjin Univ. (China)

This conference brings together researchers and engineers from academia, industry, and government laboratories to explore and present work in the frequency range covering approximately 20 GHz (15 mm) to 3 THz (100 μm). Terahertz (THz) technology deals with the generation and utilization of electromagnetic energy covering what is also known as the sub-millimeter wave region of the spectrum. In this region, which lies between the millimeter wave and far infrared spectral regions, materials exhibit properties that can be exploited to advantage for use over a broad range of important technologies and applications.

This conference includes low to high power sources, detectors, systems, both photonic and electronic including both optical and electronic modulated sources, detectors and systems. At THz frequencies, the primary difficulty encountered by scientists and engineers working in this field is the lack of convenient and affordable sources and detectors of terahertz radiation, but this difficulty is gradually changing as new sources and improved detectors are being developed and as the technology continues to mature and broaden. The purpose of this conference is to gather scientists and engineers from a diverse set of disciplines, who are interested in either learning more about terahertz and submillimeter and millimeter wave and RF technology, or who are contributing to the field through their own research, development or manufacturing activities. Disciplines utilizing terahertz technology include physical chemistry (certain molecules or molecular segments exhibit strong resonances in the 10 cm -1 to 100 cm -1 spectral region), military and homeland security (terahertz radiation can penetrate clothing and packing materials but is refl ected by metals and other materials), biomedical technology (tissue exhibits reflection and absorption properties that change dramatically with tissue characteristics), medical and dental, secure short-distance wireless communications (atmospheric water content prevents terahertz radiation from traveling very far), astronomy (the cold background of the universe exhibits a peak in this spectral region), space communications (where the terahertz region is wide open for use) and other disciplines where new, yet-to-be-discovered applications will undoubtedly come forth. Since the low energy associated with terahertz radiation is expected to be no more harmful than infrared or microwave radiation, safety issues are not expected to limit the use of terahertz radiation at low power levels. Papers are solicited in the following and related areas:
