Abstract
A reconfigurable intelligent surface includes a radiant layer, a sensing feeding circuit layer, a processing layer and a controlling circuit layer. The radiant layer includes at least two antennas and a plurality of reflecting units. Each of the at least two antennas is configured for sensing a polarization, a frequency or a direction angle of an incident electromagnetic wave. The reflecting units are arranged to form a reflecting surface. The sensing feeding circuit layer is signally connected to the antennas. The processing layer is signally connected to the sensing feeding circuit layer, and the processing layer is configured to produce a controlling signal corresponding thereto. The controlling circuit layer is signally connected to the radiant layer and the processing layer, wherein the controlling circuit layer receives the controlling signal and controls the reflecting units according to the controlling signal to adjust and form a reflecting electromagnetic wave.
