| Abstract: | This paper introduces a diagonalized multilevel fast multipole algorithm with spherical harmonics expansion of the k-space integrals. The algorithm changes the storage and calculation method that the traditional multilevel fast multipole algorithm has used in the k-space integrals to realize the matrix vector multiple. The performance of the algorithm is evaluated according to the processing of 3-D metal scattering problem. And the merits with faster speed and lower storage are concluded. The calculation result illustrates the high performance of the algorithm. |
