Approximate methods for solving electromagnetic coupling in electrically large cavities

摘要

This paper deals with electromagnetic coupling in or between large cavities. Since the position of the devices inside the cavities can be considered as random, an approach based on the statistics in mode stirred reverberation chambers is followed. Two examples are successively shown: the coupling to a single wire loaded at both ends and parallel to the walls of a cavity, and the coupling between two adjacent cavities through a hole in a common wall. A wire passing through the hole is also taken into account.
