Abstract
The optical response of a metasurface is controlled by actuating it via an electrical or magnetic field, temperature control, optical pumping or electromechanical actuation. The metasurface will therefore control the polarization of the incident light. The metasurface comprises an array of patch antennas. The patch antennas are in the form of asymmetrical elements, including rotated rods, cross-shapes, V-shapes, and L-shapes.
