Integrated Multipliers for Submillimeter-Wave Radio Astronomy

毫米波和亚毫米波乘法器性能的基本和实质性改进将产生更可靠的变容乘法器，在太赫兹频率上具有更高的带宽和效率，这将使在电磁频谱中探索最少和最重要的区域之一进行高灵敏度观测成为可能。这个为期三年的项目侧重于三个发展阶段。1)基于二极管的亚毫米波集成电路（MMIC）的发展，2)集成太赫兹频率下集成电路乘法器设计的电磁和器件仿真工具，以及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的发展也将对大气遥感、化学光谱学、高分辨率雷达等领域产生重大影响，并将打开太赫兹频谱区域的更多使用和更广泛的科学研究。

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.
