智能超表面技术联盟（RISTA）：2024年智能超表面技术白皮书：信道建模与仿真（英文版）

Reconfigurable Intelligent Surface (RIS) is one of the most promising techniques due to its potential capability of establishing a low cost and low power consumption communication environment. Based on configurable meta-materials, RIS is capable of adjusting the impinging wireless signal’s phase or/and amplitude, and then control its propagation direction, which makes the dynamically fluctuating wireless propagation environment programmable. Till now, a serious of RIS prototypes have been
