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…

Translation of Nanoantenna Hot-Spots by a Metal-Dielectric Composite Superlens
Zhengtong Liu, Mark D. Thoreson, Alexander V. Kildishev +1
We employ numerical simulations to show that highly localized, enhanced electromagnetic fields, also known as "hot spots," produced by a periodic array of silver nanoantennas can b…
