Future wireless networks are expected to transform to a unified communication, sensing, and computing platform with embedded intelligence and programmability, enabling ubiquitous communications between humans, robots, and other mobile devices. They will be also capable of controlling, sensing, and opti¬mizing the wireless propagation environment to fulfill the visions for low-power, high-throughput, massively-connect¬ed, and low-latency communications. Following the recent breakthroughs on the fabrication of programmable metamaterials, the holographic MIMO paradigm has lately received significant attention from both academia and industry due to its low cost, size, and weight, as well as low-power consumption hardware implementations, providing a transformative means for turning the wireless environment into a software-controlled intelligent platform with immersive sensing capability. This workshop aims to bring together practitioners and researchers from both academia and industry working on fundamental and practically relevant questions related to the many challenges arising from holographic MIMO systems for communications and sensing. It will be composed of technical sessions, a panel session, keynote talks, and a session with two relevant demos.
