Evolution of oscillations of semibounded electron plasma

For the most comprehensive study of electromagnetic oscillations in confined plasma-like media, it is necessary to solve a general problem on an evolution of an initial disturbance in it. The authors consider a heterogeneous structure, consisting of two semibounded media: a solid-state or gas plasma and nonabsorbing nondispersive medium (dielectric or vacuum). They study the evolutions of the electron distribution function and electric fields in such structures at all subsequent instants of time. The authors restrict their consideration to Coulomb plasma when one can neglect by delay effects of electromagnetic interactions. Electromagnetic properties of the plasma are described by the set of Maxwell's equations and the linearizing kinetic equation for the nonequilibrium distribution.
