Simulation of Electromagnetic Waves Propagation in the Radio Electronic Systems

Mathematical modeling of the processes of electromagnetic waves propagation in the layered magneto-dielectric mediums with losses have been presented. For such modelling, the finite integration technique was used. To truncate the investigated domain, the electromagnetic wave was divided into incident and reflected ones, and the uniaxial perfectly matched layers were applied at the domain outer boarders. These methods were modified taking into account the problem formulation with the help of the magnetic vector potential, which provide substantial reduction of the required computation resources (in two times and more). With the help of carried numerical experiments, effectiveness and correctness of usage of the proposed approach have been shown.
