Description:
Traditional materials have predetermined optical properties based on the material’s refractive index and dispersion. By judiciously patterning materials on a scale smaller than the wavelength of light, however, one can create “metamaterials” with electromagnetic responses not achievable in natural materials. Metasurfaces are optical elements with nanoscale thickness and planar profilesnthat take advantage of this subwavelength patterning to mimic and expand upon the functionality of tradit
