Magnetic Shielding for High Fields

Abstract

During the program a code was developed to predict the attenuation in a multilayer, non-linear system. This program allows modeling of shielding effectiveness for the complex case of high conductivity and high permeability layers in which the high permeability film reaches saturation. Conventional materials have limited effectiveness once they saturated but, using this code, it is possible to design a profile to increase the attenuation even at magnetic fields that saturate the magnetic layers. This is a surprising result and indicates the importance of a code that treats nonlinear, multilayer media.
