Abstract

A well-established, silver fishnet design has been further miniaturized to function as a negative-index material at the shortest wavelength to date (to our knowledge). By studying the transmittance, reflectance, and corresponding numerical simulations of the sample, we report in this Letter a negative refractive index of −0.25 at the yellow-light wavelength of 580 nm. © 2009 Optical Society of America OCIS codes: 160.4670, 260.5740. Negative-index metamaterials (NIMs) are artificially tailored composites of noble metals (such as silver or gold) and dielectrics [1,2]. This kind of material has attracted a significant amount of research attention since 2000, following the prediction of superlensing using NIMs by Pendry [3]. A near-field metamaterial superlens was successfully demonstrated soon thereafter [4]. Recently, NIM research has been further inspired by the possibility of optical cloaking [5–7]. These applications have the most to offer in the visible
