Abstract

Microwave Technologies is developing a revolutionary miniature terahertz traveling-wave microtube (TTM) that will provide sub-millimeter wave radiation for many civilian and military applications. This new concept uses a dielectric microtube in conjunction with a microscopic electron beam. The electron beam is produced by a single micron-sized emitter, which lies underneath the microtube to produce high-power terahertz electromagnetic radiation. The TTM should be easily fabricated using state-of-the-art solid-state technology, and will be a pioneering step towards combining vacuum tube technology with solid-state microfabrication technology. Some of the applications for these exciting new devices include terahertz high-resolution radar, THz chemical and biological sensing, commercial THz line-of-sight networking and ultrahigh-speed computers. A key application of the device under development will be as a miniature terahertz source for biological and chemical spectroscopy. We present detailed numerical and computational analysis of this concept. We also present initial experimental testing of a dielectric microtube designed to operate at 0.1 THz. Once successfully developed, TTMs will be the basis for a new generation of high power terahertz sources capable of producing ultrahigh frequency radiation with high efficiency in an amazingly compact and lightweight package.
