چکیده
The dynamic motions of ion-acoustic (IA) waves in plasma are studied by considering the Kappa-Cairns electron distribution. The effect of external periodic force is also considered, here. Using the reductive perturbation technique, a Korteweg-de Vries (K-dV) equation is obtained. The quasiperiodic motions of IA waves are investigated by considering two-dimensional phase portraits and time-series analysis. The effects of non--thermal parameters (i.e., $\kappa $, $\alpha $) and the strength ($f_0$) of the external periodic force on nonlinear travelling wave structures are also discussed.
