Abstract :
In this paper numerical solution of electromagnetic pulse scattering by dual layered dielectric structure has been considered. For calculation convenience propagation in two-dimensional rectangular area bounded perfectly conducting walls has been treated. Numerical algorithm has been developed using finite difference in time-domain with NVIDIA CUDA technology implementation. A finite difference method implementation for the case of computation by graphical processor has been considered. The results of numerical modeling Gaussian function pulse scattering has been shown. Comparative analysis of the CPU and GPU performance has been retrieved out. As shown, the FDTD method computation by graphical processor allows to achieve a sufficient gain of the performance.
