ELECTROMAGNETIC SOLITONS PROPAGATION ACROSS A STRONG MAGNETIC FIELD INTO PLASMAS

In this paper the analitycal and numerical study of high amplitude extraordinary wave nonlinear properties in underdense plasmas have been carried out. In slightly relativistic approach it is shown that an extraordinary wave can transform to an evalute soliton at propagation across a strong magnetic field in vicinity of electron cyclotron resonance. With help of 1-D relativistic PIC code we conducted a numerical simulation of an electromagnetic pulse transverse propagation in a magnetized plasma. The numerical experiments have been shown that a long pulse decay to a solitons sequence at its interaction with plasmas in the resonant conditions.
