A two dimensional periodic pattern of capacitive and inductive elements (12, 14) defined in the surface of a metal sheet are provided by a plurality of conductive patches (62) each connected to a conductive back plane sheet (30) between which an insulating dielectric (26) is disposed. The elements act to suppress surface currents in the surface defined by them. In particular, the array forms a ground plane mesh (24) for use in combination with an antenna. The performance of the ground plane mesh is characterized by a frequency band within which no substantial surface currents are able to propagate along the ground plane mesh. Use of such a ground plane in aircraft or other metallic vehicles thereby prevents radiation from the antenna from propagating along the metallic skin of the aircraft or vehicle. The surface also reflects electromagnetic waves without the phase shift that occurs on a normal metal surface.

Cette configuration bi-dimensionnelle d'éléments capacitifs et inductifs (12, 14) définis sur une face d'une plaque métallique est constituée de plusieurs pièces conductrices (62) connectées, chacune, à une plaque de base plane conductrice (30), un diélectrique isolant (26) venant s'interposer. Ces éléments suppriment les courants de surface sur la surface qu'ils définissent. Ce réseau forme notamment une grille tapis de sol (24) utilisable en liaison avec une antenne. Le fonctionnement de cette grille tapis de sol repose sur une bande de fréquence empêchant la propagation d'importants courants de surface dans ladite grille. L'utilisation de ce tapis de sol dans un aéronef ou d'autres véhicules métalliques permet d'éviter qu'un rayonnement émanant d'une antenne ne se propage le long du revêtement métallique de l'aéronef ou du véhicule. La surface réfléchit également les ondes électromagnétiques sans que ne se produise le déphasage survenant sur une surface métallique normale.
