Abstract

The influence of electron trapping on the propagation of an electrosound wave is investigated. It is shown, that on the stage of modulational instability the trapped particles prevent the spatial localization of the HF field. Under certain conditions the trapped particles destroy the stationary soliton. For nonstationary envelope waves the nonlinearity, connected with trapped particles, leads to a Korteveg-de Vries equation.
