Researchers in China have developed a reconfigurable intelligent surface (RIS) that harvests energy from enemy radar.
A: Indoor user equipment receiving signals from the base station (BS) via a reconfigurable intelligent surface (RIS) on a building window. B: Hardware architectures at the base station, reconfigurable ...
Reconfigurable intelligent surfaces (RIS) are engineered structures comprised of several elements known as 'meta-atoms,' which can reshape and control electromagnetic waves in real-time. These ...
