Abstract

Dispositif à métasurface (1 ) comprenant un empilement de couches comprenant une métasurface (4) comprenant un réseau bidimensionnel de pastilles conductrices (5) séparées par des ouvertures (6), les pastilles conductrices présentant des dimensions inférieures à la longueur d’onde de fonctionnement du dispositif à métasurface, le dispositif à métasurface (1 ) comprenant un ensemble d’interrupteurs (10) à base d’un matériau susceptible de passer de l’état isolant à l’état conducteur, et inversement, sous l’effet d’une variation d’un champ électrique au sein du matériau de sorte à permettre de connecter ou isoler sélectivement entre elles des pastilles conductrices, les interrupteurs étant interposés entre un premier ensemble d’électrodes (E1 ) et un deuxième ensemble d’électrodes (E2) permettant de commander le passage des interrupteurs de l’ensemble d’interrupteurs de l’état conducteur à l’état isolant, et inversement.
