要約

The paper deals with an asymptotic behavior of unknowns in an infinite system of linear equations which defines the weight factors in the Fourier expansion of the acoustic potential for a model of a waveguide with a stiff stepped bottom and a sound velocity profile variable over the depth. Knowing the asymptotic behavior of the unknowns one can use an enhanced reduction method to calculate the coefficients for normal modes. A numerical study of sound fields was performed with variable parameters of the problem.
