Mon travail porte sur la simulation numerique de la propagation d'ondes electromagnetiques dans des milieux comportant des fils parfaitement conducteurs dont l'epaisseur est beaucoup plus petite que la longueur d'onde du champ environnant.
Je cherche une methode numerique volumique efficace pour la prise en compte de fils sans avoir recours a un raffinement de maillage. La solution que nous mettons en place s'appuie sur des methodes d'analyse asymptotique pour aboutir a des schemas simples et non verrouillants.
