Own waves in a transversely inhomogeneous open cylindrical dielectric waveguide

By the point matching method, taking into account only the even electric longitudinal field components, is considered the eigenvalue problem -constant propagation in inhomogeneous dielectric waveguide. The following model is accepted: a dielectric waveguide of round cross-section with single circular heterogeneity. A result of numerical studies of the dependence of the propagation constant for different types of waves, depending on the parameters and the location of the in homogeneity, are introduced. The results of the study can be extended to the study of waveguides with a cross section of different shapes and/or contain multiple heterogeneous domains with different parameters.
