摘要

我们研究了非均质等离子体中存在被困电子时尘粒对孤子反射的影响。我们考虑了一个包含离子、被困电子和带负电尘粒的等离子体模型。在这里，我们采用了还原扰动理论（RPT）来获得修正的 Korteweg-de Vries（m-KdV）方程。m-KdV 方程的解表示不均匀等离子体系统中的孤波解。孤波解表示尘埃粒子在非均质等离子体中的各种效应。我们还讨论了在非均质密度梯度存在的情况下，孤子反射过程中孤子传播的不同模式。

Effect of Dust Particles in Soliton Reflection in the Presence of Trapped Electrons in an Inhomogeneous Plasma

The influence of dust grains on soliton reflection in the presence of trapped electrons in an inhomogeneous plasma is investigated. We have considered a plasma model having ions, trapped electrons, and negatively charged dust particles. Here, the reductive perturbation theory (RPT) is employed to obtain the modified Korteweg–de Vries (m-KdV) equation. The solution of m-KdV equation indicates the solitary wave solution in the inhomogeneous plasma system. The solitary wave solution signifies the various effects of dust particles in inhomogeneous plasma. We have also discussed the different modes of soliton propagations during soliton reflection in the presence of inhomogeneity density gradients.
