Domain decomposition method by integral equations for studying electromagnetic diffraction from large metallic structures

International audience; In this paper, we present a non-overlapping domain decomposition method by integral equations in the frequency domain for the resolution of wave scat-tering from metallic objects. The objective is to use multi-domain modelling to process multi-scale structures. This method is flexible thanks to an independance be-tween sub-domains and relying on the local resolution of these sub-domains. Moreover, the convergence is im-proved compared to a classical resolution. This method is achieved for predicting radar cross-sections, studying antennas radiation and EMC applications.
