A reconfigurable thermally actuated transmissive and reflective panel or surface is disclosed. A panel includes a metallization layer that includes unit cells configured to resonate at a desired frequency or range of frequencies. The panel includes a switch layer formed of a metal insulator transition material that is thermally controlled with a refractory heater layer to be in a metallic state or an insulator state. The state determines whether the panel operates in a reflective mode in which incident signals are reflected or a transmission mode in which incident signals are transmitted through the panel. The refractory heater layer, when provided with a voltage, generates heat to heat the switch layer and switch to the metallic state. Removing (or lowering) the voltage allows the temperature of the switch layer to drop until the switch layer transitions to the insulation state and the panel operates in the transmission mode.

The technology described herein is directed towards a reconfigurable surface device that reflects an impinging electromagnetic signal, with a phase profile determined by vertical positioning of a flexible metallic ground plane beneath metallic resonating elements of the reconfigurable surface. The vertical positioning forms different gaps between portions of the flexible ground plane and the respective metallic resonating elements above those portions, to determine the direction of the reflected beam. In one implementation, four individually linear actuators (vertical driving motors) are mechanically coupled to the corners of the ground plane of a metasurface (panel). These actuators and motors are independently controlled to establish the phase profile, by determining the amount of vertical positioning of each corner of the flexible ground plane to steer the reflected beam. The low-cost design can operate to steer millimeter wavelength beams in many wireless communication scenarios.
