BBMM is a simple, fast multipole accelerated, electric field integral equation (EFIE) solver for free space electromagnetic scattering problems. The purpose of this project is to provide an easily accessible program to serve as a reference for students and researchers.

Under the hood, it uses the proven Rao-Wilton-Glisson basis functions with Galerkin testing for discretizing the EFIE. The resulting matrix equation is then solved iteratively using a Krylov subspace solver, such as the GMRES. The matrix-vector products are accelerated using a multi-level fast multipole method.
