Frequency-dependent loss and dispersion are typically modeled with a power-law
attenuation coefficient, where the power-law exponent ranges from 0 to 2. To facilitate …

The sea bottom is generally modeled as a fluid for many of the shallow water acoustic
propagation modeling applications. The inherent assumption is that the bottom does not …

The nonlinear progressive wave equation (NPE) is a time-domain formulation of the Euler
fluid equations designed to model low-angle wave propagation using a wave-following …

The frequency dependence of the attenuation of acoustic waves in various types of materials
continues to be a topic of research. The present discussion is prompted by recent papers …

The depth-dependent shear wave speed in marine sediments is much less than both the
compressional and water column sound speeds. The neglect of shear in geoacoustic …

This Postdoctoral Fellowship has three main goals. The first is to quantify the water sediment
interaction zone boundary condition for acoustical applications, using theory, numerical …
