Test methods for electromagnetic shielding materials
B.A. Kinningham,D.M. Yenni +1 more
TL;DR: The NBS flanged coaxial fixture method demonstrated significant advantages over the other tests evaluated its dynamic range and was consistently higher than any of the other methods evaluated; it allows the evaluation of both near-and far field shielding (using theoretical calculations), so that both emission and susceptibility problems could be addressed; and there was less variability from location to location.

Low-Frequency Shielding of a Circular Loop Electromagnetic Field Source
TL;DR: In this article, the problem of low-frequency shielding of a loop axially perpendicular to a plane shield of infinite extent is analyzed by 1) the thin shield work of S. Levy, 2) solution of the vector wave equation, and 3) application of the transmission theory of shielding of Schelkunoff.
New Theoretical Expressions forPredicting Shielding Effectiveness for thePlane Shield Case
Abstract: The problem of the electromagnetic shielding effectiveness of a thin, plane metal sheet of infinite extent on the electromagnetic field generated by a circular loop field source with uniform current I is solved by application of the quasi-near and near field approximations to the exact integral expressions. The results are shown to be in close agreement with experimental data as well as numerical integration results. Also, they are similar to the results obtained from the plane wave shielding theory of Schelkunoff.
