Abstract: | The application of the mixed finite-element method for the analysis of dispersion curves of the cylindrical waveguides with a gradient loading is considered. The test results of the algorithm and the calculations of systems with a variable refractive index are presented. The initiation of complex waves in layered waveguides is shown. |
