Stable Propagating Waves and Wake Fields in Relativistic Electromagnetic Plasma

摘要

Stable propagating waves and wake fields in relativistic electromagnetic plasma are investigated.The incident electromagnetic field has a finite initial constant amplitude meanwhile the longitudinal momentum of electrons is taken into account in the problem.It is found that in the moving frame with transverse wave group velocity the stable propagating transverse electromagnetic waves and longitudinal plasma wake fields can exist in the appropriate regime of plasma.
