High refractive index, polarization insensitive nano-rod based plasmonic metamaterials for lenses

摘要

An optical material is described. The optical material includes at least one layer of a metamaterial. Each layer of metamaterial includes a matrix material and a plurality of nano-particles. The plurality of nano-particles are geometrically arranged in an array within the matrix material such that the layer of metamaterial has a high positive refractive index based on a cooperative plasmon effect at a predetermined electro-magnetic radiation (EMR) wavelength relative to the refractive index of the matrix material without the nano-particles.
