Abstract[English]
An electrically tunable metasurface (300) and a method for modulating propagation characteristics of an incident plane wave (502,504) are disclosed. The electrically tunable metasurface (300) comprises: i) a plurality of scatterer rings (302), each one of the plurality of scatterer rings (302) including bow-tie radiator elements (304), the bow-tie radiator elements (304) in a corresponding scatterer ring (302) having a same geometric configuration; and ii) a plurality of electrodes (310,314), each electrode (310,314) being configured to provide a biasing voltage (V1,V2) to the corresponding scatterer ring (302). The method comprises: i) receiving, by an electrically tunable metasurface (300), the incident plane wave (502,504); and ii) modulating the propagation characteristics of the incident plane wave (502,504) by providing specific biasing voltage (V1,V2) to the corresponding scatterer rings (302).[French]
Une métasurface électriquement accordable (300) et un procédé de modulation des caractéristiques de propagation d'une onde de plan incident (502,504) sont divulgués. La métasurface électriquement accordable (300) comprend : i) une pluralité d'anneaux de diffuseur (302), chacun de la pluralité d'anneaux de diffuseur (302) comprenant des éléments de radiateur en forme d'étrier (304), les éléments de radiateur en forme d'étrier (304) dans un anneau de diffuseur correspondant (302) ayant une même configuration géométrique ; et ii) une pluralité d'électrodes (310,314), chaque électrode (310,314) étant configurée pour fournir une tension de polarisation (V1,V2) à l'anneau de diffuseur correspondant (302). Le procédé comprend : i) la réception, par une métasurface électriquement accordable (300), de l'onde de plan incident (502,504) ; et ii) la modulation des caractéristiques de propagation de l'onde de plan incident (502,504) en fournissant une tension de polarisation spécifique (V1,V2) aux anneaux de diffuseur correspondants (302).
