Abstract. Mixed finite elements are applied to cylindrical waveguides with arbitrary filling mode computation. For the solution of the field approximation problem in the zero point the ideal conductor is introduced to the waveguide axis. Test results have high accuracy. The method opportunities are considered for the problems with arbitrary filling.

Keywords: dispersion curves, waveguides, mixed finite elements.
