The technology described herein is directed towards a reconfigurable intelligent surface (RIS) based on microelectromechanical systems (MEMS) technology, in which metallic MEMS micro-actuators are integrated into unit cells of the RIS. Dual ring-shaped metallic cantilevers, resulting from unit cell fabrication, operate as electrothermal actuators in the unit cell's resonating pattern. A controlled voltage can be separately applied to each ring-shaped cantilever, deforming (bending up) each ring at its non-anchored (free) portion from its generally flat non-actuated state via joule heating. The amount of vertical displacement of the free portion of each ring when voltage is applied separately changes the structure of the unit cell's geometry based on each amount of applied voltage, whereby analog-like tuning of the unit cell's characteristics (including phase shift) is obtained. When combined with the voltage-controlled phase shifts of other unit cells of the RIS, beamforming of a reflected incoming electromagnetic wave is facilitated.
