    "abstract": "We develop an approach to use nanostructured plasmonic materials as a\nnon-magnetic negative-refractive index system at optical and near-infrared\nfrequencies. In contrast to conventional negative refraction materials, our\ndesign does not require periodicity and thus is highly tolerant to fabrication\ndefects. Moreover, since the proposed materials are intrinsically non-magnetic,\ntheir performance is not limited to proximity of a resonance so that the\nresulting structure has relatively low loss. We develop the analytical\ndescription of the relevant electromagnetic phenomena and justify our analytic\nresults via numerical solutions of Maxwell equations.",
