9320183 WEIKLE This research program will investigate methods for improving the performance of submillimeter Schottky receivers and reducing the requirement for high-power THz local oscillator sources through the use of planar, surface-channel diodes and subharmonic mixing. Schottky diodes operating above 1 THz will be integrated into quasi-optical structures that permit the use of lower-frequency, relatively low-power local oscillators. The RF properties of different diode geometries and integrated planar antennas will also be studied. This program is expected to result in more reliable Schottky diode receivers with reduced local oscillator requirements at THz frequencies. This development will help to open up this important region of the spectrum for millimeter wave imaging, radar, atmospheric chemistry, and monitoring of atmospheric ozone.

9320183 WEIKLE 该研究计划将研究通过使用平面、表面通道二极管和分谐波混频来提高亚毫米肖特基接收器性能并降低对高功率太赫兹本地振荡器源的需求的方法。 工作频率高于 1 THz 的肖特基二极管将集成到准光学结构中，从而允许使用较低频率、相对低功耗的本地振荡器。 还将研究不同二极管几何形状和集成平面天线的射频特性。 该计划预计将产生更可靠的肖特基二极管接收器，并降低太赫兹频率下的本地振荡器要求。 这一进展将有助于为毫米波成像、雷达、大气化学和大气臭氧监测开辟这一重要的频谱区域。
