Flooding is a major problem facing Southern African region. The region has been experiencing flood for the past two decades. This flood event has been exacerbated in recent years by global weather pattern known as La Nina which cools ocean waters in

We apply the equivalence particle principle to several nonlinear Schrodinger equations (NLSEs) that model the propagation of a spatial beam with logarithmic law nonlinearity. Using this principle, expressions for acceleration, spatial frequency, spat

This paper presents the one soliton modulated cosine solution to the Biswas–Milovic equation with log law nonlinearity. The approach is to use the ansatz method to obtain relations for the velocity of the soliton or spatial Gausson with equations f

Maxwell's equations for a metallic and nonlinear Kerr interface waveguide at the nanoscale can be approximated to a (1+1) D Nonlinear Schrodinger type model equation (NLSE) with appropriate assumptions and approximations. Theoretically, without losse

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, expressi

We continue a study of the equivalence particle principle applied to an optical spatial soliton which is a "narrow filament" that maintains its existence in a waveguide. Using this principle, expressions for acceleration, spatial frequency, spatial p

Short pulse spectral content becomes modified while propagating in dispersive media. However, in dispersive nonlinear media, optical pulses resulting in solitary waves maintain their existence if proper balance is established between nonlinear self-p
