Abstract

The paper deals with the fast prediction of the electromagnetic shielding performances of aperture loaded by resistive thin film coatings. The electromagnetic shielding problem is addressed by the finite element method (FEM). The shielding configuration is analysed by modeling open apertures by an equivalent sheet impedance that is introduced in the FEM computational domain as an internal artificial boundary. Equivalent loaded apertures are also proposed to reduce the computational cost. Simple test cases of plane wave shielding problems are presented to show the efficiency of the proposed method.
