Kinetic theory of electromagnetic ion waves in relativistic plasmas
- Centre for Nonlinear Physics, Department of Physics, Umeaa University, SE-901 87 Umeaa (Sweden)
A kinetic theory for electromagnetic ion waves in a cold relativistic plasma is derived. The kinetic equation for the broadband electromagnetic ion waves is coupled to the slow density response via an acoustic equation driven by a ponderomotive force-like term linear in the electromagnetic field amplitude. The modulational instability growth rate is derived for an arbitrary spectrum of waves. The monochromatic and random phase cases are studied.
