[HTML][HTML] A scaled mapping parabolic equation for sloping range-dependent environments
Parabolic equation solutions use various techniques for approximating range-dependent
interfaces. One is a mapping approach [MD Collins et al., J. Acoust. Soc. Am. 107, 1937–
1942 (2000)] where at each range the domain is vertically translated so that sloping
bathymetry becomes horizontal, and range dependence is transferred to the upper surface.
In this paper, a scaled mapping is suggested where the domain is vertically distorted so that
both the bathymetry and upper surface are horizontal. Accuracy is demonstrated for …
