Numerical and Analytical Study of the Behavior of the HF Electromagnetic Field on the Surface of the Thin Layer

In this work, we present a method of calculation of the high frequency electromagnetic field HF at the surface of a massive screen. This method is formulated in magnetic potential vector by taking into consideration 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 can be extended to infinity. The coupling of these two methods of calculation utilizes fictitious surface currents. This permit 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
