摘要：
Reconfigurable Intelligent Surface (RIS) breaks technological limitations of traditional wireless communication systems, it creates new opportunities for development of 5G-Adv and 6G by introducing reconfigurable communication environment. RIS system architecture and working principle are introduced in detail, including hardware design and beamforming method. RIS assisted wireless communication system is introduced in-depth, received signal gain and system performance are analyzed in details. Combined with indoor test, beamforming ability of RIS is verified.
