Call for papers: Special issue on reconfigurable intelligent surface aided wireless communications

Reconfigurable Intelligent Surface (RIS), also known as intelligent reflecting surface or large intelligent surface, is an emerging new physical-layer technology in the field of wireless communications. The basic idea of RIS is to deploy a reconfigurable passive array in the environment to manipulate the propagation of electron-magnetic (EM) waves. RIS promises a new design paradigm for wireless communications, where the wireless propagation environment can be dynamically controlled, which is substantially different from the conventional design that focuses only on the transmitter and receiver. RIS is expected to solve the blockage problem, increase the channel capacity, promote the wireless coverage, and improve the energy efficiency for the future communication systems. Thus, it is regarded as a promising potential technology to realize the future intelligent communications from the physical layer.
