Abstract
For the model of the waveguide which is a multilayered medium with a cylindrical seamount, the asymptotic behavior of the unknowns in the corresponding infinite system is studied. The obtained asymptotic behavior of the unknowns allows us to use the method of improved reduction for finding the coefficients of the normal modes. The convergence of the algorithm is illustrated by the example of some geophysical waveguides.
