Scattering-free plasmonic optics with anisotropic metamaterials
Justin Elser, Viktor A. Podolskiy
We develop an approach to utilize anisotropic metamaterials to solve one of the fundamental problems of modern plasmonics -- parasitic scattering of surface waves into free-space m…
Far field imaging by a planar lens: diffraction versus superresolution
Nicholas A. Kuhta, Viktor A. Podolskiy, Alexei L. Efros
We resolve the long standing controversy regarding the imaging by a planar lens made of left-handed media and demonstrate theoretically that its far field image has a fundamentally…
Active metamaterials: sign of refraction index and gain-assisted dispersion management
Alexander A. Govyadinov, Mikhail A. Noginov, Viktor A. Podolskiy
We derive an approach to define the causal direction of the wavevector of modes in optical metamaterials, which in turn, determines signs of refractive index and impedance as a fun…
Highly Confined Optical Modes in Nanoscale Metal-Dielectric Multilayers
Ivan Avrutsky, Ildar Salakhutdinov, Justin Elser +1
We show that a stack of metal-dielectric nanolayers, in addition to the long- and short-range plasmons, guides also an entire family of modes strongly confined within the multilaye…
