Dr. Yang Li from Tsinghua University, China, visited C-UFO on 30th May, 2018 and gave the public talk on " Zero index on a photonic chip: physics and applications ". Prof. Qi-Dai Chen hosted the talk. ![](/__local/9/4A/A2/6EEC49E97355F2221398192401C_59D978FF_3382F.jpg?e=.jpg)
He mainly introduces the research status of metamaterials, the properties and characteristics of metamaterials and their potential application value. In particular, he introduces how to make metamaterials with micro-nano processing technology to achieve the 0 refractive index of light.
