摘要：
The axial propagation of linear and nonlinear pulses in a strongly magnetized non-neutral plasma slab is studied using a recently developed particle simulation code [Ramachandran et al. Phys. Fluids B 5, 2733 (1993)]. These pulses are generated by suddenly applying a negative potential to wail antennas on the confining walls. Theoretical predictions are compared to electrostatic particle simulations over a wide range of excitation amplitudes, and are shown to be in excellent agreement. A simple theoretical model is developed to describe the formation of the observed electron bursts and the associated wave breaking that arises for very large antenna potentials.
