Large-amplitude Electron Oscillations in a Plasma Slab

Abstract

Nonlinear oscillations within a plasma slab are analyzed. Two types of solutions are found, depending on the initial value of the electron density. The first represents regular oscillations within the plasma slab, while the second gives rise to explosive growth at the slab centre or at the edges. The results are discussed.Comment: 5 pages, 4 figures, to appear in Journal of Plasma Physic
