The fast-growing need to satisfy billions of mobile subscribers calls for the deployment of advanced wireless communication techniques to achieve the desired quality of service. Reconfigurable intelligent surfaces (RIS) are currently being explored to ameliorate several issues in wireless networks. RIS comprises passive elements that require limited active antennas at the base station (BS) to achieve energy efficiency and spectral gains. RIS, a key enabler for 6G wireless networks, has enormous potential to address signal loss between the transmitter and the receiver. RIS can be deployed to enhance the reliability of wireless systems in 6G and beyond. Additionally, RIS can be employed to mitigate interference in wireless communication systems. RIS supports simultaneous wireless information and power transfer and enhances security at the physical layer. Compared to relay-assisted technologies, RIS offers low cost and high efficiency. However, the computational complexity issue in RIS-assisted wireless networks design is still an issue that needs to be addressed holistically. In order to address this issue, among others, there is a need for a book that investigates the characteristics, benefits, and limitations of RIS deployment in advanced wireless communication systems. The book analyzes the design and applications of RIS in 6G and beyond. In particular, the book considers the application of RIS, aiding efficient wireless signal transmission from the base station to the mobile station, considering several practical constraints. The book is a high-quality reference to practitioners, industry and academic researchers, scientists, and engineers in the fields of wireless communications and networking, information theory, signal processing, 5G and 6G networks, antennas design, sensing and localization, channel modeling and propagation measurement, reconfigurable intelligent surfaces, ICTs, and others. Additionally, graduate and senior undergraduate students will find the book very useful for courses within the broad aspects of wireless communications. Finally, the book is structured into 17 chapters collected from industry experts, world-class academics, and researchers, resulting in a diverse and high-quality reference for the readers.
