For Robust mmWave Performance: Capture Thermo-Structural Effects with Multiphysics Simulation

摘要

In this article, a conventional EM simulation was extended to include thermo-structural effects on a mmWave filter's performance. Through multiphysics analyses, the performance of a high speed communication system component, a cascaded mmWave cavity bandpass filter, was shown to be robust under harsh environmental conditions. This modeling methodology can be used to simulate the performance and reliability of many different types of sensitive components and subsystems in extreme operating environments, identifying potential problems early in the development process and saving costly redesigns.
