The field of wireless communications is witnessing significant advancements with the integration of reconfigurable intelligent surfaces (RIS) and metasurfaces. These technologies are enabling innovative solutions for enhancing signal coverage, improving communication performance, and ensuring secure data transmission. Recent developments focus on optimizing the design and deployment of RIS and metasurfaces in various wireless communication systems, including multi-cell MIMO, UAV communications, and sensing networks. Noteworthy papers in this area propose novel optimization frameworks, beamforming designs, and security protocols that leverage the unique capabilities of RIS and metasurfaces. For instance, some studies investigate the use of RIS to enhance physical-layer security, while others explore the potential of metasurfaces for superheterodyne transmitters and cryogenic scalable quantum applications. Overall, the field is moving towards the development of more sophisticated and adaptive wireless communication systems that can effectively utilize RIS and metasurfaces to improve performance and security. Notable papers include Joint Beamforming and Position Optimization for IRS-Aided SWIPT with Movable Antennas, which proposes an efficient algorithm for maximizing the weighted sum-rate of information decoding receivers, and The Battle of Metasurfaces: Understanding Security in Smart Radio Environments, which analyzes the interaction between competing metasurfaces and their implications for wireless security.
