Prof Henry Chung (Chair Professor of EE) and Dr TANG Ho Tin (2025 PhD graduate) have been awarded the Gold Medal at the Silicon Valley International Inventions Festival (SVIIF) 2025. The winning project is titled “Innovative Gate Drive Technology: Incorporating Self-adaptive Gate Driving, Health Monitoring, and Crosstalk Mitigation for Wide Band Gap Devices Prevalent in Modern Energy Systems”. Designed for advanced power devices used in modern energy systems, this smart gate driver, i.e. a kind of power amplifier, reduces electrical interference, helps the devices last longer, and checks their condition to keep them running at their best.
SVIIF, the world’s largest innovations competition, showcases cutting-edge inventions from around the world and provides a unique platform for inventors to receive internationally recognized awards for excellence in innovation. More details can be found at CityUHK News Centre.
Prof Din-ping Tsai (Chair Professor of EE), in collaboration with Prof Yuri Kivshar from the Australian National University, has been awarded the 2025 Top Ten Advances in Metamaterials in China (Basic Research) for their recent work published in Physical Review Letters and titled “From Local to Nonlocal High-𝑄 Plasmonic Metasurfaces”. They found a generalized law ‘Inverse square root law’, that builds up the connection between high-loss localized surface plasmon resonances (LSPRs) and low-loss surface plasmon polaritons (SPPs), enabling a significant reduction in dissipation loss and paving the way for novel applications.
The award was presented at the 4th China Metamaterials Conference (CMMC 2025). The conference is dedicated to advancing fundamental research, as well as research in design, manufacturing, and device applications. It serves as a significant platform that connects academia and industry, fostering academic dialogue, technical collaboration, and the advancement of technology.

Prof Gengbo WU (Assistant Professor of EE), Dr Yuansong ZENG (Research Fellow, SKLTMW), and Dr Jin CHEN (Postdoc, SKLTMW) have published a paper in the top journal – Nature, on 14 May 2025. The paper titled “Bulk–spatiotemporal vortex correspondence in gyromagnetic zero-index media” is a collaborative work with scholars coming from The Hong Kong University of Science and Technology, Fudan University, Wuhan University, Shenzhen University, and University of Southampton.
This paper can be found at Nature. To give you a glimpse of the research work, here is a brief introduction: Here we experimentally realize gyromagnetic double-zero-index metamaterials possessing both double-zero-index features and non-reciprocal hallmarks. We discover and demonstrate that a spatiotemporal reflection vortex singularity is always anchored to the Dirac point of the metamaterial, with the vortex charge being determined by the topological invariant leap across the phase transition. This establishes a unique bulk–spatiotemporal vortex correspondence that extends the protected boundary effects into the time domain and characterizes topological phase-transition points. Based on this correspondence, we propose and experimentally demonstrate a mechanism to deterministically generate optical spatiotemporal vortex pulses with firmly fixed central frequency and momentum. Our findings uncover connections between zero-refractive-index photonics, topological photonics and singular optics, which might enable the manipulation of space-time topological light fields using the inherent topology of extreme-parameter metamaterials.
