Creator:: Elser, Justin, Podolskiy, Viktor A., Salakhutdinov, Ildar, and Avrutsky, Ivan
Abstract:: The authors analyze electromagnetic modes in multilayered nanocomposites and demonstrate that the response of a majority of realistic layered structures is strongly affected by the nonlocal effects originating from strong field oscillations across the system, and is not described by conventional effective-medium theories. They develop the analytical description of the...

Creator:: Elser, Justin, Wangberg, Robyn, Podolskiy, Viktor A., and Narimanov, Evgenii E.
Abstract:: The authors study perspectives of nanowire metamaterials for negative-refraction waveguides, high-performance polarizers, and polarization-sensitive biosensors. They demonstrate that the behavior of these composites is strongly influenced by the concentration, distribution, and geometry of the nanowires, derive an analytical description of electromagnetism in anisotropic nanowire-based metamaterials, and explore the limitations of...

Creator:: Govyadinov, Alexander A., Podolskiy, Viktor A., and Noginov, M.
Abstract:: We derive an approach to determine the causal direction of wavevectors of modes in optical metamaterials, which, in turn, determines signs of refractive index and impedance as a function of real and imaginary parts of dielectric permittivity and magnetic permeability. We use the developed technique to demonstrate that the interplay...

Creator:: Podolskiy, Viktor A., Kuhta, Nicholas A., and Milton, Graeme W.
Abstract:: We analyze the performance of a planar lens based on realistic negative index material in a generalized geometry. We demonstrate that the conventional superlens design (where the lens is centered between the object and the image) is not optimal from the resolution point of view, develop an analytical expression for...

Creator:: Hoffman, Anthony J., Sridhar, Aishwarya, Braun, Phillip X., Alekseyev, Leonid, Howard, Scott S., Franz, Kale J., Cheng, Liwei, Choa, Fow-Sen, Sivco, Deborah L, Podolskiy, Viktor A., Narimanov, Evgenii E., and Gmachl, Claire
Abstract:: We report on a novel class of semiconductor metamaterials that employ a strongly anisotropic dielectric function to achieve negative refraction in the midinfrared region of the spectrum, ~8.5–13 μm. We present two types of metamaterials, layered highly doped/undoped heterostructures and quantum well superlattices that are highly anisotropic. Contrary to other...
