A study of the efficiency of the parallelization of a high frequency electromagnetic approach for the computation of radiation and scattering considering multiple bounces Original Research Article

Different schemes for the parallelization of a new algorithm to accelerate the Ray-Tracing for computing the electrical field radiated from or scattered by complex objects using high frequency techniques are presented. This algorithm is based on a combination of the Angular image-Buffer (AZB), the Space Volumetric Partitioning (SVP) and the A*Heuristic search method. The algorithm is very useful for different applications. Basically, four kinds of analysis can be done with the tool: radiation pattern of antennas, electromagnetic field values in observation points in the near field, mutual coupling between antennas and propagation at indoor/outdoor environments. A computational analysis is shown for the different strategies of parallelization for shared and distributed memory computers.
