The field of wireless communication is moving towards the integration of emerging technologies such as reconfigurable intelligent surfaces (RISs), aerial RISs, and active stacked intelligent metasurfaces (ASIMs) to enhance energy and spectral efficiency. Researchers are exploring the use of these technologies in various applications, including satellite-terrestrial edge computing networks, vehicular visible light communication systems, and internet of things (IoT)-cellular networks. The focus is on developing innovative solutions that can address the challenges of physical layer security, interference mitigation, and quality of service (QoS) provisioning in these systems. Notable papers in this area include: The paper on Multi-User SLNR-Based Precoding With Gold Nanoparticles in Vehicular VLC Systems, which proposes a novel approach to mitigate LED correlation using gold nanoparticles. The paper on Secure Satellite Communications via Multiple Aerial RISs, which investigates the use of aerial RISs to enhance physical layer security in satellite communications. The paper on Enhancing Energy and Spectral Efficiency in IoT-Cellular Networks via Active SIM-Equipped LEO Satellites, which demonstrates the potential of active SIM-equipped LEO satellites to improve energy and spectral efficiency in IoT-cellular networks.
