Negative Refractive Index in Artificial Metamaterials
arXiv:physics/0603216 · doi:10.1364/OL.31.002483
Abstract
We discuss optical constants in artificial metamaterials showing negative magnetic permeability and electric permittivity. Using effective field theory, we calculate effective permeability of nanofabricated media composed of pairs of identical gold nano-pillars with magnetic response in the visible spectrum.
