The field of integrated sensing and communication (ISAC) systems is witnessing significant developments, driven by the increasing demand for seamless interaction between sensing and communication technologies. A key trend in this area is the utilization of reconfigurable intelligent surfaces (RIS) to enhance the performance of ISAC systems. Researchers are exploring innovative designs and optimization techniques to improve the accuracy and efficiency of these systems. Notably, the use of RIS-aided cooperative ISAC networks is showing great promise for applications such as structural health monitoring, which requires high precision and reliability. Furthermore, the development of flexible intelligent metasurfaces and correlated RIS designs is enabling the creation of more efficient and adaptable sensing and communication systems. Overall, the field is moving towards more sophisticated and integrated solutions that can support a wide range of applications, from wireless sensing to high-precision monitoring. Noteworthy papers include: Multi-IRS Aided ISAC System, which proposes a hybrid multi-IRS architecture to improve communication and sensing performance. A Correlation-Based Design of RIS reduces power consumption and simplifies control circuitry by exploiting correlations between phase shift values.
