études de Structures Filtrantes Diélectriques non Rayonnantes


Des études théoriques et expérimentales sur les résonateurs diélectriques de différentes géométries en structures diélectriques non rayonnantes ont été développées pour la réalisation de dispositifs sélectifs en fréquence, comme filtres coupe-bande, passe-bande et directifs, dans la bande des fréquences millimétriques.
