Abstract: With the further development of related research on metamaterials and metasurfaces, the concept of Intelligent Reflecting Surface (IRS) was proposed. IRS uses a large number of passive reflective elements integrated on the plane to intelligently configure the wireless propagation environment through software programming, so as to improve the performance of the wireless communication system. Compared with the traditional relay base station, IRS has the advantages of low cost, low power consumption and easy deployment. Therefore, IRS and IRS-assisted wireless communication are one of the important technologies in the future development of the communication field. By investigating and sorting out the current status of IRS research, the development and applications of IRS and IRS-assisted wireless communication are introduced in terms of the basic concepts, development history, characteristics and advantages of IRS, and the basic concepts and research directions of IRS-assisted wireless communication. Future development of IRS is also discussed.
