Abstract: After reviewing the functionalities, advantages, and practical applications of reconfigurable intelligent surface (RIS)-assisted wireless communication systems and RIS-assisted radar sensing systems, the feasibility, advancements, and prospects of RIS-aided integrated sensing and communication (ISAC) are revealed. Then, the challenges and opportunities of deploying RIS in various ISAC scenarios including near-field communication and sensing, bi-static sensing, and wideband systems are discussed, as well as the promising future directions of various RIS deployments in ISAC systems including active, multiple, and unmanned aerial vehicle (UAV)-mounted RIS. It is believed that artificial intelligence will provide more effective and robust solutions to related research.  
Keywords: RIS; ISAC; reflection coefficient design; multi-antenna system; beamforming design
