Abstract :
An efficient domain decomposition approach for electromagnetic field analysis of complex 3D antennas is presented. The method combines the Moment Method (MM), the Multilevel Fast Multipole Algorithm (MLFMA), Physics Optics (PO) and the Domain Decomposition Method to provide fast and accurate analysis of arbitrary metallic and dielectric/magnetic structures, and to solve very large scattering problems. Moreover, in order to minimize memory and time requirements, a parallelization process has been carried out by using the Message Passing Interface (MPI) algorithm. The code has been validated in many applications providing accurate predictions compared with measurements. As an example, a dual-band reflectarray is analyzed to check the performance of the proposed code.
