Abstract: Holographic metasurfaces have emerged as a pivotal technology in advancing sixth-generation (6G) networks, facilitating smart environments that manipulate electromagnetic (EM) waves to enhance signal coverage and robustness. High data rate communication and high-resolution sensing are essential for 6G wireless networks. Yet, developing a unified hardware system that integrates communication and sensing (ISAC) at these standards remains a formidable challenge. A critical issue is the EM interference between the sensing and communication signals, which can undermine both the effectiveness and reliability of the system. This paper introduces a novel architectural approach for holographic metasurfaces which operate across mmWave for communication and integrate THz graphene antennas for sensing, crucial for the deployment of future 6G networks. We outline potential applications of this integrated THz-mmWave system and discuss various challenges and considerations essential for its effective implementation and commercial viability, aiming to ensure robust, efficient, and scalable network performance.
