Yu.I.Papkova Interconnection of a model of hydroacoustic flat-layered waveguide on the hard base with the Pekeris waveguide |
Acoustic bulletin, Vol. 16 ¹ 1, (2013-2014) |
| The paper deals with studying of dependence between two types of waveguides with a "liquid" bottom. In the limiting case, the discrete part of the spectrum of the Pekeris waveguide is shown to coincide with the spectrum of a waveguide in which properties of the bottom are simulated as a "liquid" layer on a rigid foundation. The numerical results at varying system parameters are analyzed. |
