Abstract[English]
A reflective meta-surface (102) and a method (500) of manufacturing the reflective meta-surface (102) is provided. The reflective meta-surface (102) comprises a plurality of unit cells (112) arranged in a pre-defined pattern. The plurality of unit cells (112) is formed by disposing a loading plane (206) on a first top surface (204) of a first dielectric substrate (202). A second dielectric substrate (211) is disposed on the first top surface (204) of the first dielectric substrate (202) sandwiching the loading plane (206). Further, disposing a conducting plane (216) on a second top surface (212) of the second dielectric substrate (211). The conducting plane (216) is a negative conjugate of the loading plane (206).[French]
Est proposée une métasurface réfléchissante (102) et un procédé (500) de fabrication de la métasurface réfléchissante (102). La métasurface réfléchissante (102) comprend une pluralité de cellules unitaires (112) agencée selon un motif prédéfini. La pluralité de cellules unitaires (112) est formée en disposant un plan de chargement (206) sur une première surface supérieure (204) d'un premier substrat diélectrique (202). Un second substrat diélectrique (211) est disposé sur la première surface supérieure (204) du premier substrat diélectrique (202) prenant en sandwich le plan de chargement (206). L'invention propose en outre la disposition d'un plan conducteur (216) sur une seconde surface supérieure (212) du second substrat diélectrique (211). Le plan conducteur (216) est un conjugué négatif du plan de chargement (206).
