چکیده
|
In the present paper,we see the effect of shapes of perturbing pulses on the evolution of electromagnetic solitons in a plasma having nonrelativistic ions and electrons. for this,we make use of imex scheme in our simulations,which is an invariant scheme for the two-fluid plasma flow equations. in particular,the impact of ion-to-electron mass ratio,electron-to-ion temperature ratio and the width of perturbing pulse is examined on the phase velocity,peak amplitude and width of the solitons. © 2018,the author(s).
