TMATDG: applying TDG methods to multiple scattering via T-matrix approximation
This is an incremental software contribution for researchers working on numerical simulation of wave scattering, providing a practical tool for polygonal geometries.
The paper presents a MATLAB package that combines Trefftz Discontinuous Galerkin methods with T-matrix approximation to solve multiple scattering problems for Helmholtz equations, enabling efficient handling of polygonal obstacles.
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. 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.
