|Title||S-WAVES IN A NONLINEAR, LEFT- HANDED MATERIALS AND FERRITE LAYERED STRUCTURE|
Nonlinear magnetostatic surface wave in a slab waveguide structure has been investigated. The behavior of TE nonlinear waves in an optically nonlinear film is given. Electromagnetic surface waves propagating in a nonlinear dielectric film bounded by a ferrite cover and left handed material substrate (a medium with both negative dielectric permittivity and negative magnetic permeability-LHM) are examined theoretically. The new mathematical results are expressed in terms of physical parameters of the system. A dispersion relation based on Jacobian Elliptic Functions is derived. The general dispersion relation is derived and analyzed numerically. Dispersion curves labeled with optical power density at the lower film boundary, detailed plots of the variation of electric field amplitude as the wave number changes It is shown that the proposed waveguide structure depends on the refractive index efficiently controlled by varying the frequency.
