Abstract :
To facilitate the analysis of large problems, in this paper, all the full matrices are stored in a sparse form and the PFFT method is employed to accelerate all the matrix-vector products appearing in both hand sides of the matrix equation for the moments. The present method can deal with much larger problems than the traditional MoM-AWE method since the PFFT achieves great reduction in memory requirement and computation time.
