| Summary: | Spatial solitons are the solutions of nonlinear partial differential equations describing the propagation of
optical beams in Kerr type nonlinear medium. This paper studies the scattering of a spatial solitons of the
Cubic-Quintic Nonlinear Schrödinger Equation (C-Q NLSE) on an interface between two nonlinear media.
The scattering process will be investigated by variational approximation method and by direct numerical
solution of C-Q NLSE. This variational approximation method has been used to analyse the dynamic of the
width and center of mass position of a soliton during the scattering process. Meanwhile, a direct numerical
simulation of C-Q NLSE is run to check the accuracy of the approximation by using the same range of
parameters and initial condition. The results for direct numerical simulation of CQNLSE for soliton
parameters are quite similar with the variational equation. The studies showed that soliton can be reflected
by or transmitted through the interface, also the nonlinear surface wave can be formed depending on the
parameters of interface and initial soliton. |
