Description

technical field [0001] The invention belongs to the technical field of materials and communication, and in particular relates to the structural design of an active reconfigurable intelligent reflective surface of an integrated solar cell. Background technique [0002] It is expected that the capacity of communication networks will increase by a thousand times in the next ten years, and ubiquitous wireless connections will become a reality. However, highly complex networks, high-cost hardware and increasing energy consumption will be the key issues facing future wireless communications. For example, the large-scale MIMO and ultra-dense networking in the key technologies of 5G increase hardware costs and energy consumption due to the deployment of a large number of base stations and antennas; the expansion of terahertz spectrum from sub-6G to millimeter wave requires more complex Signal processing and more expensive power-hungry hardware. For now, the manufacturing process of...
