Spectrum Control of Light with Metasurface

Structural Colors from All-Dielectric Surface Resonator

My second research interest is investigating how to control the apparent color of materials using all dielectric nanostructures, or the so-called Physical Colors. Different from conventional paint, which rely on the chemical properties of the dye molecules, physical colors rely solely on the geometry of the nanoscaled-materials. Therefore, with physical colors it is possible to achieve much better reflectance, longer durability and even dynamic tuning of the material's color.
