Parallel-in-Space-Time Analysis of Electromagnetic Interference in Electronic Enclosures

摘要

There has been a growing and pressing need to rapidly evaluate the electromagnetic (EM) interference and susceptibility of electronic devices inside complex enclosures. To address this need, this paper leverages the time-domain wave physics to develop first-principles computational and predictive models. The temporal multi-scale challenge in analyzing longtime cavity transient dynamics is addressed by a new time-evolution Green's function and a space-time domain decomposition method. The research overcomes the time-step limitation and the sequential-in-time barrier, and achieves first-time a parallel-in-time capability for solving transient cavity problems. The results are valuable for the broadband analysis of EM emission and interference, shielding effectiveness and integrity, and integrated design of electronics and enclosures.
