Summary:
Recently, Chebyshev PSTD has become a flexible and efficient approach in EM transient analysis. The major computation cost for PSTD method comes from the evaluation of differentiation matrix multiplication. In order to further improve the efficiency, the fast multipole algorithm is exploited. The fast multopole algorithm is a basic hierarchical method which is first developed in celestial mechanics. Recently it has been employed to analysis cardinal series in computational physics. Make use of the similarity of N-body problem and Chebyshev interpolation, a new fast multipole accelerated PSTD method is developed in this paper.
