Approaches for handling sloping fluid-solid interfaces with the parabolic equation method
Michael D. Collins, Adith Ramamurti
Several methods for handling sloping fluid-solid interfaces with the elastic parabolic equation are tested. A single-scattering approach that is modified for the fluid-solid case i…

Multisector parabolic-equation approach to compute acoustic scattering by noncanonically shaped impenetrable objects
Adith Ramamurti, David C. Calvo
A lesser-known but powerful application of parabolic equation methods is to the target scattering problem. In this paper, we use noncanonically shaped objects to establish the limi…
