Scalable Electromagnetic Scattering Computations

Abstract

In this paper, we summarize the results of our efforts in developing a scalable distributed memory fast electromagnetic integral equation solver. The massively parallel scattering code, called LSSP, is based on a Galerkin discretization of the combined field integral equation (CFIE) using the RWG basis functions. The resulting matrix equation is then solved using a parallel GMRES solver. It uses the distributed memory parallel MLFMA library called ScaleME for evaluating matrix-vector products and Message Passing Interface (MPI) for inter-processor communication. Furthermore. once the solution is obtained, the bistatic RCS is computed using a parallelized, MLFMA based far field evaluation algorithm. The objective of this paper is to present some recent results demonstrating the scalability of the code for solving realistic problems.
