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…
Plane Wave Discontinuous Galerkin methods for scattering by periodic structures
Armando Maria Monforte
This thesis explores the application of Plane Wave Discontinuous Galerkin (PWDG) methods for the numerical simulation of electromagnetic scattering by periodic structures. Periodic…
