Acoustics of Layered Media II presents the theory of sound propagation and reflection of
spherical waves and bounded beams in layered media. It is mathematically rigorous but at …

In this article, stable Padé approximations to the function 1+ z are derived by choosing a
branch cut in the negative half-plane. The Padé coefficients are complex and may be …

In this paper a system of equations for wide‐angle one‐way elastic wave propagation in
arbitrarily heterogeneous media is formulated in both the space and wavenumber domains …

In the 20th century, an important contribution to the modeling of wave propagation prediction
is the Parabolic Equation (PE) approximation method. This did not happen until the last …

After the parabolic equation method was initially applied to scalar wave propagation
problems in ocean acoustics and seismology, it took more than a decade before there was …

The three types of algorithms that have been developed for solving parabolic wave
equations are compared. Until recently, it was necessary to choose between the finite …

The study of seismic body waves is an integral aspect in global, exploration and engineering
scale seismology, where the forward modeling of waves is an essential component in …

This paper is concerned with transparent boundary conditions (TBCs) for wide angle
“parabolic” equations (WAPEs) in the application to underwater acoustics (assuming …

Inverse problems in ocean acoustics and methods for solving them are discussed. Some of
the unknowns for remote sensing problems are sound speed in the ocean, sediment …

Numerous contributions have been made in the enhancement of the Parabolic Equation
(PE) approximation method, which has been shown to be a useful tool for solving realistic …
