9521521 Jones The millimeter- and submillimeter-wave range has long been of vital interest to radio astronomers and atmospheric scientists, and is becoming increasingly important for commercial applications such as automotive collision avoidance systems and surveillance radar. Unfortunately, the development of millimeter- and submillimeter-wave systems has been slow and costly. At present, the most serious challenge for millimeter- and submillimeter wave circuit designers is the realization of reliable, moderate power low noise and compact solid state sources. This proposal addresses these issues by focusing on the investigation of high performance Transferred Electron Oscillators for 100-300 Ghz. The goals of this three year research program are 1) Theoretical and experimental investigation of novel GaAs, InP, and GaN Stable Depletion Layer Transferred Electron Devices for improved 150-300 Ghz operation in second-harmonic cavities, 2) Advanced computer-aided design of Transferred Electron Devices and the associated second-harmonic oscillator cavities, and 3) Design, construction and testing of high reliability, digitally controlled, second-harmonic TEO systems. This project will involve a variety of research areas, including millimeter- wave solid state device theory, device fabrication, advanced computer-aided design of nonlinear circuits and oscillator system design. The research effort is an Academic-Industry collaboration under the Grant Opportunities for Academic Liaison with Industry (GOALI) program. The University of Virginia researchers will work in close collaboration with J.E. Carlstrom Company, Litton Solid State, Santa Clara, CA. This GOALI program will enable collaboration with the two leading corporations selling advanced TEO systems. Future progress in the development of millimeter- and submillimeter-wave systems for scientific and commercial applications will depend critically on the availability of reliable and compact solid state sources, and implementation of this research program will be an important step toward this goal. ***

毫米波和亚毫米波范围长期以来一直是射电天文学家和大气科学家的重要兴趣，并且在汽车防撞系统和监视雷达等商业应用中变得越来越重要。不幸的是，毫米波和亚毫米波系统的发展一直缓慢而昂贵。目前，毫米波和亚毫米波电路设计者面临的最严峻挑战是实现可靠、中等功率、低噪声和紧凑的固态源。本提案通过研究100-300 Ghz的高性能转移电子振荡器来解决这些问题。这项为期三年的研究计划的目标是：1)理论和实验研究新型GaAs， InP和GaN稳定耗尽层转移电子器件，以改善150-300 Ghz的二次谐波腔；2)转移电子器件和相关的二次谐波振荡器腔的先进计算机辅助设计；3)设计，构建和测试高可靠性，数字控制，二次谐波TEO系统。本项目将涉及多个研究领域，包括毫米波固态器件理论、器件制造、非线性电路的先进计算机辅助设计和振荡器系统设计。这项研究工作是在“与工业界学术联络资助机会”（GOALI）计划下的学术与工业界合作项目。弗吉尼亚大学的研究人员将与J.E. Carlstrom公司密切合作，该GOALI项目将与两家销售先进TEO系统的领先公司合作。未来毫米波和亚毫米波系统在科学和商业应用方面的发展进展将主要取决于可靠和紧凑的固态源的可用性，而本研究计划的实施将是朝着这一目标迈出的重要一步。＊＊＊
