Laser Gate: Multi-MeV electron acceleration and zeptosecond e-bunching
A. E. Kaplan, A. L. Pokrovsky
Relativistically-intense laser beam with large field gradient ("laser gate") enables strong inelastic scattering of electrons crossing the beam. This process allows for multi-MeV e…
Evanescent waves in photonic crystals and image of Veselago lens
A. L. Efros, C. Y. Li, A. L. Pokrovsky
It is shown that negative electric permittivity and magnetic permeability recently discovered in a photonic crystal in the vicinity of the Gamma-point are properties of propagating…
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…
Propagation of waves in metallic photonic crystals at low frequencies and some theoretical aspects of left-handed materials
A. L. Pokrovsky, A. L. Efros
An analytical theory of low frequency electromagnetic waves in metallic photonic crystals with a small volume fraction of a metal is presented. The evidence of the existence of suc…
