The Decomposition of the Angular Spectrum Domain in the Parallel Multilevel Fast Multipole Algorithm

摘要

This paper discusses the decomposition of the angular spectrum domain in the parallel Multilevel Fast Multipole Algorithm (MLFMA), including the equational scheme, the strip scheme and the block scheme. The characteristics and the applicable principles of three methods are analyzed theoretically and numerically. The experiment results show that the block scheme is very efficient for enlarging the parallel scale, and can significantly improve the parallel efficiency.
