Title (EN) CONTINUOUS BEAM STEERING WITH MULTIPLE-GATED RECONFIGURABLE METASURFACES
(FR) ORIENTATION DE FAISCEAU CONTINU AVEC MÉTASURFACES RECONFIGURABLES À GRILLE MULTIPLE
Abstract:
(EN) An array of unit cells allows beam steering of an incident electromagnetic wave. Each unit cell has a back reflector, a conductive oxide between gate dielectrics, and an antenna. Voltage bias applied to different layers enables the accumulation or depletion of charges at the top and bottom interfaces of the conductive oxide. The charge accumulation and depletion regions control the refractive index of the material, enabling control of the reflected electromagnetic wave.
(FR) Un réseau de cellules unitaires permet une orientation de faisceau d'une onde électromagnétique incidente. Chaque cellule unitaire comprend un réflecteur arrière, un oxyde conducteur entre des diélectriques de grille, et une antenne. La polarisation de tension appliquée à différentes couches permet l'accumulation ou l'appauvrissement de charges au niveau des interfaces supérieure et inférieure de l'oxyde conducteur. Les régions d'accumulation et d'appauvrissement de charges contrôlent l'indice de réfraction du matériau, permettant la commande de l'onde électromagnétique réfléchie.
