Abstract
We consider propagation of short electromagnetic pulses in a magnetize d plasma. A self-consistent system of equations describing wake-held g eneration in the weakly nonlinear limit is derived. Due to the externa l magnetic field, the generated wake field becomes partially electroma gnetic. The equations are applicable for arbitrary directions of propa gation as compared to the external magnetic field. The conservation la ws for the system are discussed in detail. The energy decrease rate an d the frequency decrease rate of the short pulse are determined.
