摘要：
Information metasurfaces have become one of the research hotspots in the field of physics and information, because of the ability of manipulating electromagnetic waves. A series of research progress in the field of wireless communications based on information metasurfaces was introduced. Information metasurface can manipulate electromagnetic waves in real time and directly process digital coding information, and can further perceive, understand, even memorize, learn and recognize information, which makes it show great potential in the field of wireless communications. Firstly, the research progress of channel modeling was introduced and the channel improvement that information metasurfaces could achieve when they worked as a wireless relay. Secondly, the application of information metasurface in the new transmitter system was also introduced, which modulated the amplitude or phase of the carrier waves. Thus several simplified transmitter architectures could be realized. Thirdly, the realization of several new wireless communication systems using the information of the near field, far field and scattering field of the information metasurface was introduced. Finally, the future wireless communication based on information metasurface was summarized and prospected. Copyright ©2022 Infrared and Laser Engineering. All rights reserved.
