Prof. Yun Lai received the PhD degree (Physics) from the Hong Kong University of Science and Technology (HKUST) in 2005. He worked as a Research Associate in the Department of Physics in HKUST until 2011. From 2011 to 2018, he became a Professor in Soochow University in Suzhou, China. In 2018, he joined the School of Physics in Nanjing University as a Professor. 


Prof. Lai's research interests include metamaterials/metasurfaces, photonic and phononic crystals, nanophotonics and plasmonics, etc. He has published more than 160 SCI papers on high-impact journals, including Science, Nature Materials, Nature Communications, Science Advances, Physical Review Letters/X, Light Science & Applications, Optica, etc. Total citations exceed 7000. He has pioneered some seminal concepts and applications of artificial structures, such as cloaking at a distance and illusion optics, double-zero media as effective void space, hybrid elastic solids with polarization selectivity, clearly transparent materials with diffuse reflection, omnidirectional Brewster effect and anomalous Brewster effect, zero-spacing waveguide arrays and photonic circuits, interface metasurfaces with combined functions of antireflection and wavefront control, soundproof acoustic meta-cage, etc. These breakthroughs have been reported by famous science media like Science, Nature, Physics Today, etc. He has published 4 book chapters and given more than 50 invited talks. He has been granted 20 Chinese patents and 2 US patents.

Prof. Lai's research interests include metamaterials/metasurfaces, photonic and phononic crystals, nanophotonics and plasmonics, etc. He is currently focused on:

1. Breaking some classical limitations in optics, electrodynamics and acoustics, such as the conflict between diffuse reflection and transparency, the bottleneck of dense integration in waveguide systems, the bottleneck of bandwidth in absorptive materials, etc.

2. Optical invisibility, illusion and light-field display.

3. Zero-refractive-index optics and applications.

4. Metamaterials for wireless communications.

5. Energy harvesting and wireless transfer.

6. Non-Hermitian physics.

7. Other original ideas.
