Research activities (sorry, only french text)
Je travaille actuellement sur les thèmes de recherche suivants :
- Le développement de nouvelles conditions transparentes pour la diffraction d'ondes en domaine non borné. L'objectif est de pouvoir traiter des milieux anisotropes (élastiques en particulier) et des jonctions de guides ouverts. Ce travail fait l'objet d'une collaboration avec Sonia Fliss, ainsi qu'avec Eliane Bécache et Christophe Hazard de POEMS, Antoine Tonnoir de l'INSA de Rouen, Simon Chandler Wilde de l'Université de Reading et Vahan Baronian du CEA List.
- La propagation des ondes électromagnétiques dans des milieux dont les constantes changent de signe, en particulier en présence de singularités de l'interface. Ce travail fait l'objet d'une collaboration avec Lucas Chesnel de l'équipe IDEFIX de l'INRIA.
- L'étude de configurations telles qu'une perturbation d'un milieu de référence est "invisible" (pour une ou plusieurs ondes incidente, pour une ou plusieurs fréquences). En collaboration avec Lucas Chesnel (équipe DEFI de l'INRIA) et Vincent Pagneux (du LAUM), nous développons une méthode permettant de calculer pour une perturbation donnée les fréquences où se produit l'invisibilité.
- Je développe avec Luiz Faria de POEMS une méthode permettant de résoudre des équations intégrales sur des frontières infinies, l'idée étant d'introduire une dilatation analytique comme dans les PMLs. Nous appliquons actuellement cette idée au problème de l'hydrodynamique navale linéarisé.
- En collaboration avec Florian Monteghetti de l'ISAE, Lucas Chesnel et Christophe Hazard, nous cherchons à calculer les valeurs propres du problème de transmission intérieur lorsque le contraste d'indice change de signe en un point de la surface de l'objet.
