摘要

This paper presents a Parallelized Multilevel Fast Multipole (MLFMA) Moment Method (MoM) code for analyzing the scattering and radiation from electrically large complex bodies modeled by Non-Uniform Rational B-Spline Surfaces (NURBS). The bodies are represented by NURBS surfaces which are discretized without remeshing the original geometry. The basis and testing functions are defined and conformed to the exact representation of the geometry. This code has been parallelized using Message Passing Interface (MPI) and it has been successfully applied to the study of large bodies including complex and periodic multilayer structures where the real size and shape are very important.
