About his speech: „Reconfigurable Intelligent Surface Aided Communication”

The need of high-speed and energy-efficient wireless connectivity has stimulated vast research efforts on developing new wireless communication technologies. Among many candidate solutions, reconfigurable intelligent surface (RIS) has been proposed as an attractive technique to fulfill the increasing need of green communications, thanks to the recent advances on metamaterials and microelectromechanical systems (MEMS). A RIS is a meta-surface equipped with integrated electronic circuits that can be programmed to adjust an incoming electromagnetic field. In this way, a RIS acts as an artificial scatter that constructively or destructively reflect the signal transmitted over the air can be reflected in a controlled manner with very low power consumption. Besides, a RIS can be implemented using low-cost hardware and easily integrated with existing infrastructure. These salient features of RIS creates additional degrees of freedom to combat severe signal attenuation or even blockage commonly encountered in wireless communications. For example, a RIS can be flexibly attached on the wall of a building or mounted on the top of the roof in a cost-effective manner. Some initial studies have confirmed the superiority of RIS over current solutions of green communications and envision massive deployment of RIS in sixth generation (6G) communication systems. While RIS is promising for future wireless networks, there remain numerous challenges to overcome before it can be successfully implemented in the real world.
