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.

Abstract: A membrane for water collection may include a sheet having a top surface and a bottom surface, and a plurality of conical structures disposed on the top surface of the sheet, the conical structures comprising a hydrogel material. Each conical structure of the plurality of conical structures may have a height of 1 mm to 50 mm, wherein height is measured from the top surface of the sheet to an apex of a conical structure. Each conical structure of the plurality of conical structures may have an apex angle of 10 to 60 degrees.

Abstract: An optical modulation device includes a plasmonic nano-antenna layer, a metal layer that faces the plasmonic nano-antenna layer, and a permittivity variation layer and a dielectric material layer between the plasmonic nano-antenna layer and the metal layer. An active area formed in the permittivity variation layer according to an external signal may function as a gate that controls optical modulation performance.
