Diffraction of the wave $H_{10}$ by the below-cutoff section of a partially dielectric-filled waveguide has been considered. The problem is solved in an exact electrodynamic statement. Mathematical modeling is done by the generalized scattering matrix method. Propagation constants are obtained by differentiation with respect to a parameter. The dependence of numerical modeling results on the number of modes is studied. The results of the numerical analysis and physical experiments are compared.
