A Study On Metaoptics

Abstract

Metasurface is a new nano-fabricated material, which can manipulate properties of light to the point of achieving negative refraction. Metalenses are flat optics devices composed of sub-wavelength nanostructures that allow to locally control the properties of transmitted light wave (amplitude, phase, and polarization). Majors development have been made with metalenses in the last few years; for a recent review see [1].
