Tunable graphene-based reflectarray element for reconfigurable beams

Tunable reflective elements based on graphene patches are proposed for reconfigurable-beam reflectarray antennas. The complex conductivity of graphene can be dynamically varied when an electric field is applied, allowing to control the phase of the ...
