Abstract:

The long-range objective is to develop and apply microscopic phase space methods and global path integral constructions to gain a deeper theoretical and computational understanding of electromagnetic, seismic, and acoustic direct and inverse wave propagation problems. Specifically, this project focuses on the development of new multidimensional algorithms for direct forward acoustic propagation and generalized acoustic tomography at the level of the reduced scalar Helmholtz equation. The introduction and widespread application of the parabolic paraxial approximation marked a significant advance in wave propagation modeling for ocean seismo-acoustic and other strong channeling environments. In many respects, this is a most natural motivation for the application of phase space factorization and path integral methods to the Helmholtz equation. JHD
