Background. The aim of this work is to study the problem of electromagnetic TE- waves propagation in a plane nonlinear inhomogeneous dielectric waveguide.
Materials and methods. The author used general methods of the theory of bound-ary value problems, the semi-conversion method (reduction of the differential equa-tion to the integral equation using the Green's function), the contracting mapping method.
Results. The researcher has obtained a dispersion equation and proved existence of dispersion equation’s roots (propagation constants). The regions of localization of the propagation constants have been found. Numerical results (graphics of dispersion curves and eigenfunctions of the problem) have been presented.
Conclusions. The obtained results can be used in the study of the problem of coupled electromagnetic waves propagation.
