Accurate and efficient propagation modeling is a topic of ongoing interest for a variety of underwater acoustic applications. A significant example is provided by Matched Field Processing, where a large number of acoustic replica fields must be computed in order to match a particular measurement or physical parameter of interest. Here the two numerical facets are particularly important-accuracy is required faithfully to represent the physical reality of the particular scenario being modelled, and speed is required to facilitate efficient generation of a sufficient number of replica fields to adequately sample the model parameter space.
