Self-Consistent Treatment of Plasma Expansion in the Presence of Electron PLasma Wave

The hydrodynamic modification of an expanding plasma near the reflection point of an electron plasma wave is investigated by simultaneously solving the wave equation together with the steady-state hydrodynamic equations. The electric field and electron density fluctuation of the plasma wave are derived in a self-consistently steepened density profile while the density jump and its dependence on the wave amplitude are also determined.
