Abstract

We present a MATLAB package for the solution of multiple scattering problems, coupling Trefftz Discontinuos Galerkin methods for Helmholtz scattering with the T-matrix method. The method applies to both impenetrable and penetrable scatterers and relies on plane wave discrete spaces; the DtN-TDG formulation for the transmission problem is new. We rely on the TMATROM package to numerically approximate the T-matrices and deal with multiple scattering problem, providing a framework to handle scattering by polygonal obstacles.
