Abstract:

This paper proposes three methods for improvement of MLFMA including fixed side-length subdivision, assignment of weight of translation factor, and optimization for storing kernel arrays. Using these methods, one can reduce memory requirements and accelerate matrixvector multiplication. Numerical results show the validity of the optimizing methods.

Key words: electromagnetic scattering, translation factor, MLFMA
