Shielding Effectiveness Measurements of a Shielded Window: Comparative Results Obtained Using Mode-Stirred and Anechoic Chambers

摘要

This paper discusses results of shielding effectiveness (SE) testing of a shielded window in a Mode-Stirred Chamber (MSC) and in an anechoic chamber. This paper will show that the agreement between the MSC and anechoic chamber SE data is good when a large number of aspect angles are tested in the anechoic chamber and when the same equation (with modifications appropriate for the chamber of interest) is used to compute shielding effectiveness. The data presented will also be shown to support findings of similar SE tests, conducted by an independent agency, on a cover panel and gasket.
