Analysis of a dual-band reflectorarray by using a full wave moment method code

Abstract

This work presents an efficient and powerful approach for electromagnetic field analysis of complex 3D bodies. The method is able to provide 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 Characteristics Basis Function Method (CBFM) 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.
