We consider the isovelocity hydroacoustic waveguide with a bottom composed of a liquid intermediate layer and a half-space. Damping in a layer and a half-space is taken into account. Critical modes frequencies subject to the layer depth are determined. Frequency characteristics of the wave numbers, the modulus and the phase of reflection coefficient, the bottom input impedance, the modal absorption coefficients, the phase and the group velocities of normal waves are calculated as well. |
