Frequency-domain simulations of a negative-index material with embedded gain
Yonatan Sivan, Shumin Xiao, Uday K. Chettiar +2
We solve the equations governing light propagation in a negative-index material with embedded nonlinearly saturable gain material using a frequency-domain model. We show that avail…
Tunable magnetic response of metamaterials
Shumin Xiao, Uday K. Chettiar, Alexander V. Kildishev +3
We demonstrate a thermally tunable optical metamaterial with negative permeability working in the visible range. By covering coupled metallic nanostrips with aligned nematic liquid…
Yellow-light Negative-index Metamaterials
Shumin Xiao, Uday K. Chettiar, Alexander V. Kildishev +2
A well-established, silver fishnet design has been further miniaturized to function as a negative-index material at the shortest wavelength to date. By studying the transmittance,…
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…
Non-Magnetic Cloak without Reflection
Wenshan Cai, Uday K. Chettiar, Alexander V. Kildishev +2
In an electromagnetic cloak based on a transformation approach, reduced sets of material properties are generally favored due to their easier implementation in reality, although a…
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…
