SAR and thermal computations with the use of parallel FDTD algorithm

Abstract

In the following paper a two-dimensional parallel finite difference time-domain algorithm (FDTD) is presented. It uses a decomposition of a space domain into sub-areas. The shapes of the dielectrics are approximated by the groups of rectangles, described by coordinates. In addition, the parallel algorithm was equipped in the specific absorption rate and temperature increases calculation modules. The paper also contains the results of the efficiency research into two types of the connection topology of the computation nodes. The computations were made on a homogeneous cluster of personal computers.
