THE ANALYSIS OF NONLINEAR PLATE DIELECTRIC WAVEGUIDE WITH NETWORK METHOD

This paper presents a so called equivalent transmission line method for the analysis of multilayer dielectric waveguide involving nonlinear dielectric. By introducing the equivalent transmission line model of nonlinear dielectric and linear dielectric, the electromagnetic field problem about the nonlinear dielectric waveguide can be equivalent to a circuit problem. The eigen-equation governing the nonlinear dielectric waveguide can be obtained by using the transversal resonance technique. Finally, the multilayer dielectric waveguides involving saturable or non-saturable nonlinear dielectric are simulated, and the relations between the propagating power of TE mode and the normalized wavenumber are given. The results obtained are in good agreement with that in the references.
