- Abstract
Research work in question is devoted to the study of the motion of a particle in a highly ionized plasma. For the simulation, we used the PIC method (Particle In Cell) considered to be the first method to have been developed historically for the simulation of the Vlasov Maxwell or Vlasov Poisson equations. The Particle-in-Cell (PIC) method is a numerical technique used to simulate the behaviour of charged particles (such as electrons and ions) in electromagnetic environments, such as plasmas and electron beams. This method is commonly used in plasma physics, particle beam simulation and other areas of physics where the interactions between charged particles and electromagnetic fields are crucial. The ESW are observed in satellite electric field waveform data as isolated sinusoids, i.e. as unipolar pulses (a positive electric field peak or a negative electron field peak), bipolar pulses (a single-cycle wave with a positive electron field peak followed by a negative peak, or vice versa) and tripolar pulses (a continuous wave composed of two positive electron field peaks with an intermediate negative peak, or vice versa). By their very nature as isolated pulses observed in waveform data, they are classified as non-linear waves. The one-dimensional electrostatic particle simulations we have performed involve two electron beams and an ion beam moving along a static magnetic field. The density ratio of the electron beams and the thermal velocities of the electron and ion beams are chosen to have bistream instability (bi-flux instability).
