Weikle9987104毫米波和亚毫米波乘法器性能的根本性和实质性改进将产生更可靠的变容管乘法器，其带宽和效率在太赫兹频率下得到改善，这将使电磁频谱中最少探索和最重要的区域之一的高灵敏度观测成为可能。 1）基于二极管的亚毫米波集成电路MMIC的开发，2）用于太赫兹频率IC乘法器设计的电磁和器件仿真工具的集成，3）集成乘法器系统的全面研究，包括级联乘法器级的动力学。亚毫米波MMIC的开发也将对大气遥感、化学光谱学、高分辨率雷达，并将开启太赫兹光谱区域，以供更广泛的使用和更广泛的科学调查。

Weikle9987104Fundamental and substantial improvements in the performance of millimeter and submillimeter-wave multipliers will produce more reliable varactor multipliers with improved bandwidth and efficiency at terahertz frequencies which will enable high-sensitivity observations in the one of the least explored and most important regime of the electromagnetic spectrum.This three-year program focuses on three phases of development. I) development of diode-based submillimeter-wave integrated circuits MMIC's, 2) the integration of electromagnetic and device simulation tools for IC multiplier design at terahertz frequencies, and 3) a comprehensive investigation of integrated multiplier systems, including the dynamics of cascaded multiplier stages.The development of submillimeter-wave MMIC's will also have significant impact on fields such as atmospheric remote sensing, chemical spectroscopy, high-resolution radar and will open the terahertz region of the spectrum for greater use and broader scientific investigation.
