Abstract
We study theoretically and numerically the nonlinear propagation of ion acoustic waves (IAWs) in plasma. The electrostatic potential in electron-ion (e-i) plasma is mimicked by the cylindrical Kadomtsev-Petviashvili (cKP) equation using the traditional reductive perturbation approach. By applying the direct integration technique, the soliton solution is obtained. The results of simulations carried out numerically show that the amplitude as well as width of the soliton solution are signi…cantly in uenced by the plasma parameters. The exploration of IAWs propagation in laboratory as well as space plasmas may bene…t from the current work.
