报告摘要：Metamaterial is a kind of artificially structured materials, whose optical or mechanical responses are controlled by the geometry of its subwavelength building blocks rather than its chemical composition. As two-dimensional counterparts of metamaterials, metasurfaces offer fascinating possibilities of controlling light with surface-confined flat components, allowing a broad scope of potential applications, ranging from imaging, hologram, beam steering etc. However, the lack of efficient tunability due to the fixed conductivity of noble metal or permittivity of dielectrics is one of the key limitations holding back fundamental advances and novel applications for metasurfaces. In this talk, I will introduce a distinct class of active, tunable, and nonlinear metasurfaces that enables a number of novel applications including super-resolution imaging, 1D hologram, and active modulation of digital surface waves

报告人简介：Prof. Yu LUO obtained his Ph.D. in physics from Imperial College London, UK, in 2012, and B.E. degree in Electronic & Information Engineering from Zhejiang University, China, in 2006. He then remained in Imperial College London as a research associate after graduation. In 2015, he joined the School of Electrical and Electronic Engineering, Nanyang Technological University, as an assistant professor. Prof. Luo’s research interests focus on the design of metamaterials and plasmonics from fundamental aspects to various practical applications. He is well known internationally in the field of plasmonics and metamaterials worldwide. His recent work has results in a number of high-impact journal publications in Nature, Science, PNAS and PRL and has been highlighted by many scientific magazines and public media, including Nature Photonics, Nature Physics, Physics World, Phys.org, BBC News, Guardian, etc.
