La Methode des Bases Réduites et son application aux problèmes de diffraction des ondes électromagnétiques.
We start with presenting parametrized electromagnetic scattering problems of perfect electric conductors (PEC-scattering) before we introduce the Reduced Basis Method (RBM) to solve such problems in a many-query context. The RBM is a completion to existing well-established techniques for PEC-scattering, and parametrized problems in general, to compute the Radar Cross Section (RCS) for many wave-numbers, directions of incident plane waves and polarizations.
We return to the PEC-scattering framework and present some numerical examples thereof and finish by a brief overview on how we tackled the multiple scattering problem in a parametrized setting.
