Non-linear Propagation of Ion-Acoustic Solitary and Shock Waves in Three Component Plasmas with Nonthermal and Trapped Electrons (original) (raw)

An attempt have been taken to study ion-acoustic (IA) solitary and shock wave in theoretically in three component electron-ion plasmas. To do this, a non-linear propagation of IA solitary wave have been considered in unmagnetized plasmas containing mobile positively charged cold inertial ions, negatively charged Maxwellian ions with non-thermal and trapped electrons respectively. The shock wave have also been studies for above system. The well-established reductive perturbation method has been employed to derived standard solitary and shock wave equation. The solutions was also derived to study their characteristic behaviour with parametric regims.
