Electrically Actuated Liquid-Metal Unit Cell for an Intelligent Reflecting Surface
A liquid-metal unit cell for an intelligent reflecting surface is presented. The unit cell is reconfigured through the continuous electrowetting (CEW) of liquid metal. Actuating the liquid metal mimics the extension of the copper element, enabling two unit-cell states that have a ~200° reflection phase difference at 3.1 GHz.
