Dans cette thèse, nous étudions, d'un point de vue théorique et numérique, l'imagerie micro-ondes. Mathématiquement, il s'agit de résoudre un problème inverse : reconstruire les coefficients diélectriques (permittivité et conductivité) à l'intérieur d'un matériau ou d'un tissu à l'aide de mesures surfaciques du champ électrique. Ce problème est modélisé par les équations de Maxwell pour le champ électrique en régime harmonique dont nous démontrons l'existence et l'unicité d'une solution dans le cas de conditions de bord mixtes. Nous nous intéressons particulièrement à la reconstruction de perturbations dans l'indice de réfraction du milieu. L'indice du milieu sain est supposé connu et, à l'aide de mesures effectuées sur l'objet d'étude, nou...
