Anomalous low temperature ambipolar diffusion and Einstein relation
A. L. Efros
Regular Einstein relation, connecting the coefficient of ambipolar diffusion and the Dember field with mobilities, is generalized for the case of interacting electron-hole plasma.…
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…
The problem of a perfect lens made of a slab with negative refraction
A. L. Efros
The problem of the principal existence of the perfect lens and superlensing is discussed. We have demonstrated that in the case of the virtual focus the idea of perfect lens based…
Dielectric photonic crystal as medium with negative electric permittivity and magnetic permeability
A. L. Efros, A. L. Pokrovsky
We show that a two-dimensional photonic crystal (PC) made from a non-magnetic dielectric is a left-handed material in the sense defined by Veselago. Namely, it has negative values…
New type of lenses based upon left-handed materials
A. L. Pokrovsky, A. L. Efros
New type of lenses which are a slab of a left-handed material embedded into a regular material is proposed. These two materials should have equal refractive indices. Lenses with a…
Sign of refractive index and group velocity in left-handed media
A. L. Pokrovsky, A. L. Efros
We argue that the widely spread opinion that the left-handed media (LHM) are characterized by a negative refractive index is misleading. Since n does not enter into Maxwell's…
