Abstract: As the late Bruce Lee famously said, ‘Be water, my friend,’ emphasizing the power of adaptability in combat. On a broader scale, this philosophy resonates deeply with the ongoing advancements in reconfigurable antennas, which offer unparalleled flexibility to enhance wireless communications. In recent years, a groundbreaking concept known as the Fluid Antenna System (FAS) has emerged, pushing the boundaries of reconfigurable antenna technology. FAS introduces unprecedented adaptability in both shape and position, not only adding a new degree of freedom to the physical layer, which is particularly important for integrated sensing and communication (ISAC) and security scenarios, but also unlocking high-resolution signal access in the spatial domain—a capability that revolutionizes multiple access techniques. 

Bio: (Kit) Kai-Kit Wong was born in Hong Kong and received the BEng, the MPhil, and the PhD degrees, all in Electrical and Electronic Engineering, from the Hong Kong University of Science and Technology, Hong Kong, in 1996, 1998, and 2001, respectively. He is Chair Professor of Wireless Communications at the Department of Electronic and Electrical Engineering, University College London after taking appointments at University of Hong Kong and University of Hull and visiting positions at Lucent Technologies, Bell Labs and Stanford University. His current research centers around 6G and beyond mobile communications. He is one of the early researchers who proposed multiuser MIMO. His first paper on multiuser MIMO was published in WCNC 2000 which appeared to be the first ever research paper on this topic. He is Fellow of CIC, IEEE and IET. He served as the Editor-in-Chief for IEEE Wireless Communications Letters between 2020 and 2023.
