Application of surface equivalence theorem for characterization of electromagnetic shielding efficiency

Abstract

We present one application of using of surface equivalence theorem for calculation the electromagnetic shielding efficiency. The problem we concerned is conductive spherical shell illuminated by an incident plane wave. The model is simulated by using MoM SIE based code, where theorem of surface equivalence is used in order to minimize propagation of numerical error through walls of the cavity. Simulation results are compared with analytical solution, and very good matching is obtained.
