Oscillatory behavior of spatial solitons in a waveguide constituted by a medium with a transverse triangular index profile is investigated. Dynamics of such solitons are analyzed using the equivalent particle principle. Using this principle, expressions for acceleration, spatial frequency, spatial period and other variables for a spatial soliton can be derived from the solution of the basic Nonlinear Schrödinger Equation. Results obtained are in good agreement with numerical simulations of the Modified Nonlinear Schrödinger Equation. Expression of the acceleration is bounded in some cases resulting in an oscillatory behavior or a 'swing effect' of the spatial soliton. We further apply the equivalent particle approach to the perturbed Nonlinear Schrodinger Equation with power law to show that the transverse acceleration also has a swing effect.
