A pitch of the unit cells is 10 nm to 1 μm. The heights of the first and the second nanobeams are: 10 nm to 450 nm where a refractive index of the substrate is more than 3.3; and 10 nm to 1 μm where the refractive index is 3.3 or less."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Metasurfaces with asymmetric gratings for redirecting light and methods for fabricating","description":"An optical system comprises an optically transmissive substrate comprising a metasurface which comprises a grating comprising a plurality of unit cells.
