Abstract
This communication presents two efficient approaches for the electromagnetic field analysis of complex 3D bodies. The first method can provide a fast and accurate analysis of arbitrary metallic and dielectric/magnetic structures and combines the moment method (MM), the multilevel fast multipole algorithm (MLFMA), physics optics (PO) and the characteristic basis function method (CBFM) to solve very large scattering problems. The second technique is based on a domain decomposition approach that divides the geometry into several parts to minimize the vast computational resources required when applying the MM. A parallelization process was carried out by using the message passing interface (MPI) algorithm to minimize the memory and time requirements for each simulation. A dual-band reflectarray was successfully analyzed to compare the performance of both codes.
