Journal ArticleDOI
Interparticle Coupling Effects on Plasmon Resonances of Nanogold Particles
TL;DR: In this article, the authors investigate the coupling between pairs of elliptical metal particles by simulations and experiments and demonstrate that the resonant wavelength peak of two interacting particles is red-shifted from that of a single particle because of near-field coupling.
Journal ArticleDOI
Terahertz magnetic response from artificial materials.

TL;DR: It is shown that magnetic response at terahertz frequencies can be achieved in a planar structure composed of nonmagnetic conductive resonant elements and suggested that artificial magnetic structures, or hybrid structures that combine natural and artificial magnetic materials, can play a key role in teraHertz devices.
Journal ArticleDOI
Broadband Ground-Plane Cloak
TL;DR: An experimental realization of a cloak design that conceals a perturbation on a flat conducting plane, under which an object can be hidden, and results indicate that this type of cloak should scale well toward optical wavelengths.
Journal ArticleDOI
Negative Refractive Index in Left-Handed Materials
David R. Smith,Norman M. Kroll +1 more
TL;DR: The regime of negative index, made relevant by a recent demonstration of an effective LHM, leads to unusual electromagnetic wave propagation and merits further exploration.
Journal ArticleDOI
Probing the Ultimate Limits of Plasmonic Enhancement

TL;DR: It is found that the dominant limiting factor is not the resistive loss of the metal, but rather the intrinsic nonlocality of its dielectric response, which has implications for the ultimate performance of nanophotonic systems.
