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 matrixvector multiplication. Numerical results show the validity of the optimizing methods.
Key words: electromagnetic scattering, translation factor, MLFMA
