Reconfigurable Intelligent Surface (RIS) in the Sub-6 GHz Band: Design, Implementation, and Real-World Demonstration
Here, we first aim to explain practical considerations to design and implement a reconfigurable intelligent surface (RIS) in the sub-6 GHz band and then, to demonstrate its real-world performance.The wave manipulation procedure is explored with a discussion Soda Fountain Glasses on relevant electromagnetic (EM) concepts and backgrounds.Based on tha
