Patent ID: 8481153

Claim:
A low reflective surface coating, comprising: a conductive coating surface layer constructed of materials selected from the group consisting of metal, metal alloy, transparent conductive oxides, metal-filled composites, inherently conductive polymers, graphite or graphene-filled composites, nanotube-filled composite, fullerene-filled composite, and any combination thereof; at least one dielectric layer formed of a dielectric material; a substrate formed of conductive metallic material, wherein said substrate and said conductive coating surface layer are associated with and separated by said dielectric layer, wherein the distance between said substrate and said conductive coating surface layer is substantially equal and substantially uniform; wherein said low reflectance surface coating exhibits a reflectance which is wavelength dependent with a minimum reflection within a range of about 0% to about 20%; and wherein said conductive coating surface layer, said dielectric layer, and said substrate form a nanocavity exhibiting omnidirectional plasmonic leaky mode resonance.
