Soliton propagation in a magnetic-semiconducting medium

Abstract

The soliton solution for the nonlinear waves has been investigated in a composite magnetic-semiconducting medium. By using a hydrodynamic model of an infinite medium magnetized along the direction of propagation, a set of coupled nonlinear Zakharov equations has been derived. In the absence of carriers or magnetization, two extreme cases for the two independent decoupled nonlinear modes have been discussed. The propagation regions have also been numerically analyzed for the soliton solutions.
