Primary LanguageC++

CMoM - A C++ Method of Moments Solver

Description

CMoM is a C++ Computational Electromagnetic (CEM) solver focusing on the Method of Moments (MoM). CMoM can compute both serially and in parallel (using mpi). A pre-processor, written in python is also included to provide a graphical interface as well as read necessary geometry and create the necessary input files. The pre-processor is also used for post processing to display results and compare CMoM solutions to commercial CEM solvers (currently the only compatible commercial solver is FEKO).

CMoM is being developed and used in a Linux environment

Current Solvers

Method of Moments (MoM)

The MoM is done according to the work presented in "Electromagnetic Scattering by Surfaces of Arbitrary Shape" by Rao, Wilton and Glisson (1982).

Characteristic Basis Function Method (CBFM)

The CBFM is done according to the work presented in "Characteristic Basis Function Method: A New Technique For Efficient Solution of Method of Moments Matrix Equations" by Prakash and Mittra (2003).
