论文摘要
超导谐振器和传输线是用于毫米毫米毫米天文学的集成电路的基本构建块。准确的电路辐射损耗的准确模拟对于这些电路的设计至关重要，因为辐射损耗随频率增加，从而导致系统性能恶化。在这里，我们显示了2.5维矩的模拟器十四行诗EM的分层，该方法可以准确模拟亚毫米波共晶共振器和直链球群波导（CPWS）的辐射谐振行为。十四行诗模拟与通过374.6 GHz的共面谐振滤波器对传输的测量非常吻合。我们的十四行诗分层利用无损底物下方的人造损耗层来吸收辐射，我们使用共校准的内部端口进行解放。通过这种类型的分层，即使辐射损失是潜在的问题，十四行诗也可用于模拟超导毫米 - 毫米计的波电路。
Superconducting resonators and transmission lines are fundamental building blocks of integrated circuits for millimeter-submillimeter astronomy. Accurate simulation of radiation loss from the circuit is crucial for the design of these circuits because radiation loss increases with frequency, and can thereby deteriorate the system performance. Here we show a stratification for a 2.5-dimensional method-of-moment simulator Sonnet EM that enables accurate simulations of the radiative resonant behavior of submillimeter-wave coplanar resonators and straight coplanar waveguides (CPWs). The Sonnet simulation agrees well with the measurement of the transmission through a coplanar resonant filter at 374.6 GHz. Our Sonnet stratification utilizes artificial lossy layers below the lossless substrate to absorb the radiation, and we use co-calibrated internal ports for de-embedding. With this type of stratification, Sonnet can be used to model superconducting millimeter-submillimeter wave circuits even when radiation loss is a potential concern.
