Field Modulations of Ion Acoustic Waves in Plasma With Vasyliunas–Schamel Distributed Electrons

In this work, we have studied the potential and fields as well as stationary structures of ion acoustic mode in a plasma containing ions and Vasyliunas–Schamel distributed electrons through the derivation and analysis of the modified Zakharov–Kuznetsov (mZK) equation. This nonlinear evolution equation is derived by employing the reductive perturbative technique (RPT). The mZK equation executes the evolution of weakly dispersive waves under the simultaneous effect of nonlinear and dispersive forces. We have used numerical methods for obtaining the solutions. The results show the parametric influence on the evolution of field quantities in plasma waves.
