A finite element (FE) approach is presented to analyze the electromagnetic field in free space considering the field penetration through shields in complex configurations. The shield region is eliminated from the FE domain and substituted by an equivalent surface, where constraint conditions avoid the continuity of the tangential fields. The constraint relationships between the tangential fields on both facets of the surface are obtained by the shielding theory. Implementation of the proposed method is presented to solve the electric field wave equation using edge elements.

Abstract
A finite element (FE) approach is presented to analyze the electromagnetic field in free space considering the field penetration through shields in complex configurations. The shield region is eliminated from the FE domain and substituted by an equivalent surface, where constraint conditions avoid the continuity of the tangential fields. The constraint relationships between the tangential fields on both facets of the surface are obtained by the shielding theory. Implementation of the proposed method is presented to solve the electric field wave equation using edge elements.File in questo prodotto:
