Collisionless damping of surface plasma oscillations and possibilities of its reverse at the interaction with charged particle flows
This paper is devoted to investigation of the interaction between the charged particle flows passing through the boundary of plasma-like media and surface oscillations.
Interaction of hot electrons with two-dimensional gas in semiconductor superlattices
Abstract We have studied the interaction of two-dimensional plasmons with a beam of charged particles consisting of hot electrons arising from the effect of the electric field in a two-layer heterostructure and a superlattice. The spectra of the eigen oscillations are obtained. Kinetic equations describing the wave-particle interactions are constructed. The instability growth rates are calculated for transverse oscillations. Numerical estimates are given for the structures on the basis of semiconductor, compounds. Frequency and energetic differences are analyzed for semiconductor two-layer heterostructures and superlattices having this heterostructure as a periodic element.
Investigations of dielectric gratings using electrodynamic models based on volume integral equations
Eigenmodes of planar and cylindrical dielectric gratings (DGs) and electromagnetic wave scattering from multiplayer DGs are investigated. The DG characteristics are calculated using numerical-analytical solution of integral equations (IEs).
