REVISION OF STANDARDS FOR ATTENUATION MEASUREMENTS OF SHIELDED ENCLOSURES
Abstract
The program consists of theoretical and experimental investigations leading to an improved standard for testing shielded enclosures in the frequency range of 14 kilocycles to 10,000 megacycles. The improved standard is being formulated in terms of tests at approximately 14 kilocycles, in the neighborhood of the resonant frequencies of the room, and at 10,000 megacycles. The reasons for choosing these frequencies are; (1) shielding against low-frequency, low- impedance fields is difficult compared to other types of fields, (2) at the mid- frequencies, enclosures exhibit resonances which can significantly affect the performance of the room, and (3) at very high frequencies shielded enclosures exhibit phenomena not predictable from their performance at the lower frequencies. Two methods for evaluating shielded enclosures using low- impedance, low-frequency fields are under investigation.
