| Summary: | The parabolic equation (PE) method and separation of variables are applied to solve problems in which the ocean-acoustic parameters are independent of one of the horizontal Cartesian coordinates. This class of problems is representative of backscattering from ridgelike seamounts, horizontal coupling out of the radial direction, and other types of reverberation. Since the PE method efficiently handles nearly arbitrary variations in depth and in the other horizontal direction, it is possible and practical to solve complicated three-dimensional problems with this approach. The two-way PE is applied to backscattering problems. Solutions are compared with three-dimensional PE solutions for problems involving horizontal coupling. Problems involving elastic ocean bottoms are also considered. |
