REVISION OF STANDARDS FOR ATTENUATION MEASUREMENTS OF SHIELDED ENCLOSURES

Abstract

This report covers the work done during the second quarter of a one- year research program which began on 18 June 1958. The program consists of theoretical and experimental investigation leading to an improved standard for testing shielded enclosures in the frequency range of 14 kilocycles to 10,000 megacycles. The similarity between plane-wave propagation and propagation in a transmission line makes it possible to apply the results of transmission-line theory to the plane-wave theory of shielding. These results could, however, be obtained directly from extension of the plane-wave theory of shielding. The transmission-line analogy is especially useful in determining shielding effectiveness when the fields encountered have impedances which differ considerably from that of a plane wave.
