Journal ArticleDOI
Negative index of refraction in optical metamaterials.
Vladimir M. Shalaev,Wenshan Cai,Uday K. Chettiar,Hsiao Kuan Yuan,Andrey K. Sarychev,Vladimir P. Drachev,Alexander V. Kildishev +6 more
TL;DR: A double-periodic array of pairs of parallel gold nanorods is shown to have a negative refractive index in the optical range, which results from the plasmon resonance in the pairs of nanorod for both the electric and the magnetic components of light.
Journal ArticleDOI
Resonant Field Enhancements from Metal Nanoparticle Arrays
TL;DR: In this paper, a new theory based on the RLC circuit analogy has been developed to produce analytical values for EM field enhancements within the arrays, revealing a critical relationship between particle size and interparticle spacing.
Journal ArticleDOI
Experimental observation of localized optical excitations in random metal-dielectric films

TL;DR: In this article, Anderson localization of surface plasmon modes in a semicontinuous metal film using near-field scanning optical microscopy has been studied and the observed spectral peaks correspond to localized modes of random metal-dielectric films.
Journal ArticleDOI
Electromagnetic field fluctuations and optical nonlinearities in metal-dielectric composites
TL;DR: In this paper, a scaling theory of local field fluctuations and optical nonlinearities is developed for random metal-dielectric composites near a percolation threshold, which predicts that in the optical and infrared spectral ranges the local fields are very inhomogeneous and consist of sharp peaks representing localized surface plasmons.
Journal ArticleDOI
Plasmon modes and negative refraction in metal nanowire composites
TL;DR: It is shown that a composite of nanowires arranged into parallel pairs can act as a left-handed material with the effective magnetic permeability and dielectric permittivity both negative in the visible and near-infrared spectral ranges.
