This paper presents a FEM-BEM coupling method suitable for the numerical simulation of the electromagnetic scattering of objects composed of dielectric materials and perfect electric conduc- tors. The originality of the approach lies in part in the use of the newly proposed Sparse Cardinal Sine Decomposition SCSD) method for the BEM part of the computation and the fact that the simulation software is almost entirely written in MATLAB.
The performance of the method is illustrated by the computation of the electromagnetic scattering by an UAV-like object with two RAM regions proposed in the workshop ISAE EM 2016.
Résumé
Cet article présente une méethode de couplage de type FEM-BEM adaptée à la simulation numérique des problémes de diffraction électromagnétique d’objets composés de parties parfaitement conductrices et de matériaux diélectriques. L’originalié de l’approche réside, d’une part, dansl’utilisation de la nouvelle méthode décomposition creuse en sinus cardinal (SCSD) pour la partie BEMet, d’autre part, dans le fait que le programme de calcul est presqu’entiérement écrit en MATLAB.
La performance de la méthode est illustrée par le calcul de la diffraction électromagnétique d’un objet en forme d’UAV contenant deux régions absorbantes tel qu’il a été proposé au workshop ISAE EM 2016.
