ABSTRACT:
The accurate simulation of scattering of electromagnetic waves in three dimensions
by a diffraction grating is crucial in many applications of engineering and
scientific interest. In this contribution we present a novel High-Order Perturbation
of Surfaces method for the numerical approximation of vector electromagnetic
scattering by a periodic layered medium. For this we apply the method of Transformed
Field Expansions which delivers a Fourier collocation, Legendre-Galerkin, Boundary
Perturbation approach to solve the problem in transformed coordinates. A sequence
of numerical simulations demonstrate the efficient and robust spectral convergence
which can be achieved with the proposed algorithm.
