Description
Summary:In this work, we present a method of calculation of the high frequency electromagnetic field at the surface of a massive screen. This method is based on a formulation in magnetic potential vector by considering the quasi stationary harmonic mode. We used the finite element method to solve the problem in the structure and the method of integrals of border in the external medium which extends ad infinitum. The coupling of the two methods of calculation utilizes fictitious surface currents. What makes it possible to represent the numerical values of the fields. The representation of the latter according to the characteristics of the system constitutes information on the electromagnetic energy transmitted through the screen.
