Secure High-Resolution ISAC via Multi-Layer Intelligent Metasurfaces: A Layered Optimization Framework

Researchers Amirhossein Taherpour, Abbas Taherpour, and Tamer Khattab propose a novel layered optimization framework for ISAC (Integrated Sensing and Communication) systems. It uses stacked intelligent metasurfaces (SIM) to jointly optimize secure communication and high-resolution sensing. Their algorithm achieves a 32-61% improvement in sensing accuracy and a 15-35% enhancement in communication secrecy rates over conventional methods, establishing a new paradigm for secure, multi-functional 6G wireless networks.
