(a) Magnitude of the depth-dependent Green’s function at depth 46 m for the pressure-release bottom case; (b) transmission loss at depth 46 m for the pressure-release bottom case; (c) magnitude of the depth-dependent Green’s function at depth 46 m for the rigid bottom case; (d) transmission loss at depth 46 m for the rigid bottom case. In panels (b) and (d), the blue solid curves correspond to the solutions by the present method, and the red dashed curves correspond to the KRAKEN solutions.
