Abstract: Through the introduction of the basic concepts, methods, and applications of the reconfigurable intelligent surface (RIS), the unique ability of RIS to regulate various physical characteristics of electromagnetic waves is shown. The key technologies of RIS in space-time ma? nipulation are discussed in detail, as well as some iconic applications derived from these technologies in the field of imaging, perception, communication, radar, etc., which fully demonstrates the application prospect of reconfigurable intelligent surface in related industries.
Keywords: RIS; beamforming; nonlinear harmonic manipulation; holography; wireless communication
