Computationally-effective worst-case model of thin-wire radiation source for analysis of electromagnetic compatibility in frequency range 1 HZ - 40 GHZ

Abstract

Spurious coupling is one of key terms in electromagnetic compatibility (EMC). This term denotes a coupling between two objects, which concerned with a view to a possibility of creating electromagnetic interference by one object to another. In most cases, exact models of spurious couplings are complicated for use, because they may require detailed definition of many parameters and they may be computationally inefficient. Therefore, the analysis of EMC in complexes of radio and electronic equipment (REE) is usually performed in two stages: the worst-case models of spurious couplings are applied first (this makes it possible to estimate quickly the danger of spurious couplings and to separate indisputably safe ones), then more complicated and exact models (or measurements) are used for dangerous spurious couplings only [1].
