The parabolic equation method is the most effective approach for solving range-dependent problems in ocean acoustics. During the past three decades, many difficulties have been encountered while attempting to generalize this approach to problems involving elastic layers. With the development of an improved single-scattering solution [J. Acoust. Soc. Am. 121, 808813 (2007)], a large class of range-dependent seismo-acoustics problems can now be solved accurately and efficiently. Previous single-scattering solutions for seismic problems were based on an iteration formula, and limited by convergence problems. Since the improved solution does not require iteration, it provides the efficiency of the energy-conserving solution that has proved to be very useful for acoustics problems. The application of this approach to problems involving fluid layers is currently being investigated. [Work supported by ONR.]. |
