Localized ion-acoustic solitons in collision with dusty plasma

In this research, we investigate the characters of localized waves arriving from an electron-ion plasma into an electron-ion-dusty plasma region. For this purpose, we consider the presence of dust particles as a weak perturbation in the medium. It is shown that the ion-acoustic wave propagates with greater speed and higher energy when it interacts with dust particles. In addition, an oscillatory shock wave creates at the border of two different plasma environments that propagates in the opposite direction of the initial wave velocity. Time evolution of solitary wave and characters of created shock profile is also studied.

This research investigates the characteristics of localized waves propagating from an electron-ion plasma to an electron-ion-dusty plasma region. The presence of dust particles is considered as a weak perturbation in the medium. The study shows that the ion-acoustic wave propagates with a higher velocity and energy when interacting with dust particles. Additionally, an oscillatory shock wave is created at the border of two different plasma environments, propagating in the opposite direction of the initial wave velocity. The time evolution of solitary waves and the characteristics of the generated shock profile are also studied.
