Abstract :
Recently, the impedance boundary conditions (IBCs) for thin conductive and highly permeable shieldings have been extended to nonlinear material characteristics, which are modeled by the effective permeability. In this paper, the coupling of these nonlinear IBCs with the finite-element method (FEM) outside the shielding material is improved
