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. 

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.
