THE SIMULATION IN THE TIME DOMAIN FOR SCATTERING OF RADIO WAVES ON THE OBJECT LOCATED UNDER THE GROUND COVER

The paper discusses an analytical solution in the time domain Pocklington equation for a straight thin wire of finite length under land cover at a certain depth. This wire is excited by an electromagnetic wave. The description of the transition surface to air is carried out on a simplified model for the reflection coefficient. The analytical solution is based on the use of Laplace transform and Cauchy's theorem. The results of numerical calculations of the excited current in the time domain for different parameters - the conductivity of the medium are given. Recommendations on the use of the method of parallel computing to accelerate numerical solution of the problem are shown.
