Yu.I.Papkova The Pekeris waveguide in the case of the non-uniform sound velocity profile and absorbing bottom |
Acoustic bulletin, Vol. 13 ¹ 3, (2010) |
| A model of waveguide with an inhomogeneous sound velocity profile and attenuation in liquid bottom half-space is proposed. Within this scope, the asymptotic expressions for complex vertical wave numbers in water layer and bottom are obtained. The dependencies of the numerical results from parameters of considered system are analyzed. |
