Abstract

image

A. C. Atre et al. theoretically demonstrate a broadband metamaterial with negative indices across hundreds of nano meters in the visible and NIR spectral regime. On page 327, transformation optics is used to conformally map the negative index mode of an infinite plasmonic waveguide to degenerate electric and magnetic dipoles in a nanoscale plasmonic resonator. A periodic array of such resonators exhibits negative refractive indices at optical frequencies, as illustrated in the image of light passing through a micrometer-scale metamaterial prism.
