Predicting Electromagnetic Interference to a Terminated Wire Using Characteristic Mode Analysis

摘要

Electromagnetic coupling to realistic wireconfigurations exhibit large variations with respect to thefrequency, incident angle, and polarization of the interferingsignal. In this work, Characteristic Mode Analysis (CMA) is usedto calculate the fundamental modes of a terminated wire above aninfinite ground plane. Using the properties of the modes, thecoupled currents to the wire’s loads are predicted for differentincident excitations. Using this simple but practical wireconfiguration, we show the versatility of CMA in practicalelectromagnetic interference and coupling applications.
