Combining the Finite Element Method and a Padé Approximation for Scattering Analysis Application to Radiated Electromagnetic Compatibility Problems

Abstract

In electromagnetic wave propagation problems, it is usually necessary to compute the fields quantities over a broad frequency band. In this paper we present a 2D computationally efficient scheme, which combines the finite element method (FEM) with a Padé approximation procedure. The approach is devoted to radiation problems in unbounded space. It allows to obtain an explicit expression of the solution over a large frequency band. The ability of the model is shown in the analysis of the coupling between an electromagnetic wave and a metallic enclosure.
