Nonmagnetic nanocomposites for optical and infrared negative-refractive-index media
Nonmagnetic nanocomposites for optical and infrared negative-refractive-index media
We develop an approach to use nanostructured plasmonic materials as a non-magnetic negative-refractive index system at optical and near-infrared frequencies. In contrast to conventional negative refraction materials, our design does not require periodicity and thus is highly tolerant to fabrication defects. Moreover, since the proposed materials are intrinsically non-magnetic, their …
