Abstract

The analysis of shielding performance of ferromagnetic cylindrical cans is presented. The near field loop source is described introducing wave impedances which depend upon the orientation of the source. Hysteresis is taken into account accurately by means of a nonlinear implicit differential equation. The time domain solution procedure is based on the finite element time domain method. Results are presented considering two relevant source configurations
