Trefftz DG Approximation of the T-Matrix for Scattering by Periodic Layered Structures
Armando Maria Monforte, Andrea Moiola, Simone Zanotto
We study the scattering of time-harmonic electromagnetic waves by periodic layered gratings, modelled by the 2D Helmholtz equation. The periodic obstacle may include penetrable and…

TMATDG: applying TDG methods to multiple scattering via T-matrix approximation
Armando Maria Monforte
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 r…

Trefftz Discontinuous Galerkin methods for scattering by periodic structures
Armando Maria Monforte, Andrea Moiola
We propose a Trefftz discontinuous Galerkin (TDG) method for the approximation of plane wave scattering by periodic diffraction gratings, modelled by the two-dimensional Helmholtz…
