The paper outlines the most important results of the paraxial complex geometrical optics
(CGO) in respect to Gaussian beams diffraction in the smooth inhomogeneous media and …

The seismic ray method has found broad applications in the numerical calculation of seismic
wavefields in complex 3-D, isotropic and anisotropic, laterally varying layered structures and …

Born approximation is a commonly used approximation in the simulation of seismic wave
propagation. Calculation of the Green's function in Born approximation integral is essential …

An overview of two types of beam solutions is presented, Gaussian beams and Bessel
beams. Gaussian beams are examples of non-localized or diffracting beam solutions, and …

Soundfield imaging is a special analysis methodology aimed at capturing the directional
components of the acoustic field and mapping them onto a domain called “ray space”, where …

An initial study is performed in which dynamically focused Gaussian beams are investigated
for seismic imaging. Focused Gaussian beams away from the source and receiver plane …

Abstract<? A3B2 twb=. 3w?> In this study, we apply Gaussian-beam (GB) migration of
scattered teleseismic P waves to image the crust and upper mantle beneath Tibet using data …

The application of focused Gaussian beams is investigated for the seismic imaging of
common-shot reflection data. The focusing of Gaussian beams away from the source and …

This paper is the second in a sequel of two papers and dedicated to the computation of
paraxial rays and dynamic characteristics along the stationary rays obtained in the first …

Elastic-wave migration in anisotropic media is a vital challenge, particularly for areas with
irregular topography. Gaussian-beam migration (GBM) is an accurate and flexible depth …
