The field of reconfigurable intelligent surfaces and antenna systems is rapidly evolving, with a focus on enhancing wireless communication and sensing performance. Recent developments have introduced innovative concepts such as fluid integrated reflecting and emitting surfaces (FIRES), which seamlessly integrate the flexibility of fluid-antenna systems with the dual functionality of simultaneous transmitting and reflecting reconfigurable intelligent surfaces. Additionally, the use of movable antennas and rotatable antennas has shown significant potential in improving communication channel conditions and sensing capabilities. Researchers have also explored the deployment of RIS-mounted UAV networks, which can act as flying base stations to improve system performance by avoiding signal blockages. Noteworthy papers in this area include the introduction of FIRES, which has been shown to significantly outperform conventional STAR-RIS systems, and the experimental evaluation of multiple active RISs in 5G MIMO commercial networks, which has demonstrated improvements in channel rank and throughput.
