EFFECT OF BOUNDARY, ELECTRON INERTIA AND STREAMING ON LARGE AMPLITUDE WAVES IN A RELATIVISTIC PLASMA

Nonlineaer wave propagation in a relativistic bounded plasma is analysed through the pseudopotential approach by taking into account the streaming of electrons, and electron inertia. The finite geometry is seen to effect both the forward moving and reflected modes of propagation. Its dependence on the electron–ion mass ratio is also critically analysed. In the second part of the paper we study the formation of solitons through the pseudopotential approach. The variation of the form of the pseudopotential is studied with respect to the radius of the bounding system, the electron–ion mass ratio, and the streaming velocity u0. It is observed that the finite geometry and electron inertia significantly affect the solitary wave formation.
