Reconfigurable Intelligent Surfaces and Smart Radio Environments

Reconfigurable intelligent surfaces (RIS) introduce a novel paradigm in wireless communication by enabling programmable control of the radio environment. This track explores the principles and architectures of RIS, including metasurfaces capable of dynamically reflecting, refracting, and scattering electromagnetic waves. Participants will gain insight into how RIS can enhance coverage, mitigate interference, and improve spectral and energy efficiency without increasing transmit power.

The track further examines system-level integration of RIS with existing wireless and satellite networks. Topics include channel modeling, control algorithms, and joint optimization with transceivers. Practical challenges such as scalability, hardware implementation, and standardization are discussed. By enabling intelligent manipulation of the propagation environment, RIS technologies play a critical role in shaping adaptive and efficient future communication systems.
