This monograph is devoted to the systematic presentation of the theory of sound wave
propagation in layered structures. These structures can be man-made, such as ultrasonic …

The methodology of Green's function retrieval by cross-correlation has led to many
interesting applications for passive and controlled-source acoustic measurements. In all …

With the use of Fourier analysis, we describe the propagation and scattering of acoustic
waves in smoothly varying, heterogeneous media. The starting point is the generalized …

The De Wolf approximation has been introduced to overcome the limitation of the Born and
Rytov approximations in long range forward propagation and backscattering calculations …

Seismic interferometry deals with the generation of new seismic responses by
crosscorrelating existing ones. One of the main assumptions underlying most interferometry …

If singly scattered seismic waves illuminate the entirety of a subsurface structure of interest,
standard methods can be applied to image it. It is generally the case, however, that with a …

The phase-screen and the split-step Fourier methods, which allow modeling and migration
in laterally heterogeneous media, are generalized here so as to increase their accuracies for …

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 …

Acoustic reciprocity is a fundamental property of the wave equation for the total acoustic
wavefield (Rayleigh, 1878). In its most elementary form the reciprocity principle states that …

Riemannian spaces are described by nonorthogonal curvilinear coordinates. We generalize
one-way wavefield extrapolation to semiorthogonal Riemannian coordinate systems that …
