Analysis of electromagnetic scattering problems by an iterative combination of MoM with GMT using MPI for the communication

A hybrid method is proposed combining the method of moments (MoM) with the generalized multipole technique (GMT) for the efficient analysis of electromagnetic radiation and scattering problems involving metallic as well as dielectric bodies. An iterative coupling scheme is applied so that only some small changes to the MoM and GMT formulations are required, making it very attractive for the combination of already existing MoM and GMT codes. During the iteration, the MoM and GMT processes are executed in parallel, and communication is done using the message‐passing interface (MPI). © 1998 John Wiley & Sons, Inc.
