perform those functionality which can not be implemented by the materials exist in nature. Researchers founds interesting applications of meta-materials at near IR and visible spectrum. But, it becomes dicult to fabricate these 3D structure at nanoscale level. The new concept of metasurface is game changer which is 2D structure, equivalent to 3D meta-materials. It provides is a practical solution for near IR and visible wavelength. In our group, we are exploring metasurface based structure for making ultra thin high resolution display devices, lens and other applications purpose. Below image shows the SEM images and optical microscope images of high resolution all dielectric metasurfaces based color filters.
