Multi-Functional Reconfigurable Intelligent Surfaces for 6G: RIS 2.0 Architectures, Algorithms, and Applications

Multi-functional RIS architectures and algorithms for next-generation 6G networks Existing reconfigurable intelligent surface literature focuses predominantly on single-functional architectures limited to signal reflection alone.Multi-Functional Reconfigurable Intelligent Surfaces for 6G: RIS 2.0 Architectures, Algorithms, and Applications advances the field by presenting MF-RIS, a multi-functional architecture capable of simultaneous signal reflection, refraction, amplification, energy harvesting, and target sensing within unified hardware designs for 6G wireless networks.The book covers coefficient and channel models for MF-RIS configurations, beamforming techniques under non-ideal conditions, and simulations validating performance.Specific categories examined include omni-amplifying, self-sustainable, and target-sensing architectures.Chapters connect MF-RIS with federated learning, semantic communication, and AI-driven metasurface design, while addressing standardization pathways an
