Abstract
Metasurfaces relying solely on passive unit cells printed on a dielectric substrate present limited characteristics due to their intrinsic dispersions. A metasurface composed of active unit cells incorporating voltage-controlled varactor diodes, where the dispersion responses of the cells can be tailored, is proposed to overcome the limitations of passive metasurfaces. Two functionalities are numerically and experimentally demonstrated from the active metasurface used as an electronically reconfigurable reflector. First, we show that anomalous reflection properties can be produced within a broad frequency range and second, we show that the direction of the reflected beam can be scanned within an angular range.
