Abstract
A method includes providing a coating (208) over a first surface (202) of a substrate (204) and over a metasurface (200) on the first surface of the substrate; and imprinting the coating to cause a surface of the coating to have a predetermined characteristic. A device includes a substrate; a metasurface on a first surface of the substrate; and a coating on the metasurface and on the first surface of the substrate, a surface of the coating defining a functional structure.
