Abstract: As 5G networks take their final form, connectivity demands continue to increase exponentially and new services pose more constraints on the performance that end-users expect. A recent technological breakthrough that holds the potential to meet these demands is that of reconfigurable intelligent surfaces (RISs). A RIS is a nearly-passive planar structure that can be equipped with a number of scatterers significantly higher than the number of antennas in a massive MIMO array. This makes RIS potentially able to provide high data rates with very low energy consumptions. Also, RISs can be programmed in real-time to adjust the phase of the incoming signals to focus the energy toward the intended receiver or to absorb interfering signals. The tutorial will first discuss the most recent standardization activities of 5G networks and then will explain why 5G technologies will not be able to keep the pace with the exponential increase of data connectivity demands by end-users. Then, the fundamentals of RIS will be introduced and the latest results regarding the modeling and design of RIS-based wireless networks, will be presented. Propagation channel models and network deployment approaches for RIS-based systems will be discussed, and the most performing algorithms for the optimization of the radio resources of RIS-based networks will be explained, including optimal power allocation, beamforming strategies, and RIS configuration. The tutorial will also present the latest experimental results on RIS-based wireless communications and will highlight the most relevant future research directions.
