Abstract
An optical metasurface includes a substrate and a plurality of nanostructures extending from a surface of the substrate and constructed of a material having an index of refraction. The plurality of nanostructures are arranged in a plurality of unit cells comprising a dimension that is less than or equal to twice an effective wavelength of light incident on the optical metasurface, divided by the sinusoid of a deflection angle that the optical metasurface is designed to deflect the light. The plurality of nanostructures are asymmetrically arranged along a deflection direction. A unit cell aspect ratio of the plurality of nanostructures is greater than or equal to 3, and a product of the unit cell aspect ratio and the index of refraction of the material is greater than or equal to 8.
