Information Metasurfaces and Intelligent Metasurfaces

We propose to represent metamaterials by using encoded digital states, instead of the effective medium parameters, evolving a new kind of metamaterials – information metamaterials and/or information metasurfaces. Based on different digital coding sequences on the physical platform, the information metasurfaces can be used to control both electromagnetic waves and digital information flexibly, bridging the physical world and digital world. More importantly, equipped with field programmable gate array (FPGA), the information metasurface can manipulate the electromagnetic waves and process the digital messages in programmable ways. By integrating various algorithms and software in FPGA, software metasurfaces are developed by designing various machine learning algorithms in FPGA, the information metasurface can further reach artificial-intelligence (AI) capabilities. Several system-level applications of the information metasurfaces are presented, including real-time microwave imaging, new architecture wireless communications, and intelligent walls for smart home and smart cities.
