Optical Metamagnetism and Negative Index Metamaterials
Uday K. Chettiar, Alexander V. Kildishev, Wenshan Cai +3
A new class of artificially structured materials called metamaterials makes it possible to achieve electromagnetic properties that do not exist in nature. In this paper we review t…
Optical Magnetism: from Red to Blue
Wenshan Cai, Uday K. Chettiar, Hsiao-Kuan Yuan +4
A family of coupled nano-strips with varying dimensions is fabricated to obtain optical magnetic responses across the whole visible spectrum, from red to blue. The proposed approac…
Dual-Band Negative Index Metamaterial: Double-Negative at 813 nm and Single-Negative at 772 nm
Uday K. Chettiar, Alexander V. Kildishev, Hsiao-Kuan Yuan +4
This work is concerned with the experimental demonstration of a dual-band negative index metamaterial. The sample is double-negative (showing both a negative effective permeability…
A negative permeability material at red light
Hsiao-Kuan Yuan, Uday K. Chettiar, Wenshan Cai +4
Experimental demonstration of a negative permeability due to near-field coupling of periodic thin silver strips is presented. Two samples with different strip thicknesses are fabri…
Negative Refractive Index in Optics of Metal-Dielectric Composites
A. V. Kildishev, W. Cai, U. K. Chettiar +4
Specially designed metal-dielectric composites can have a negative refractive index in the optical range. Specifically, it is shown that arrays of single and paired nanorods can pr…
Negative Index of Refraction in Optical Metamaterials
Vladimir M. Shalaev, Wenshan Cai, Uday Chettiar +4
An array of pairs of parallel gold nanorods is shown to have a negative refractive index n'=-0.3 at the optical communication wavelength of 1.5 micron. This effect results from the…
