Abstract
- A new hybrid algorithm of the depth solver for the wavenumber integration technique is derived. The global matrix method is adopted as the depth solver in the ocean, where there are sources and receivers present, and the reflectivity scheme is used for calculating the wave field of the porous ocean bottom. In order to hybridize both depth solvers, a novel technique has been developed where a virtual fluid layer with zero thickness is inserted between the ocean and the porous ocean bottom. This technique makes the hybrid algorithm simple to implement and compatible with any other depth solvers for the ocean bottom. Numerical simulation shows the proposed algorithm to work well.
