A complex point-source solution of the acoustic eikonal equation for Gaussian beams in transversely isotropic media
Huang, Xingguo; Sun, Hui; Sun, Zhangqing; da Silva, Nuno (Peer reviewed; Journal article, 2020-03-11)The complex traveltime solutions of the complex eikonal equation are the basis of inhomogeneous plane-wave seismic imaging methods, such as Gaussian beam migration and tomography. We present the analytic approximations for ... -
Homotopy analysis of the Lippmann-Schwinger equation for seismic wavefield modeling in strongly scattering media
Jakobsen, Morten; Huang, Xingguo; Wu, Ru-Shan (Peer reviewed; Journal article, 2020)We present an application of the homotopy analysis method for solving the integral equations of the Lippmann-Schwinger type, which occurs frequently in acoustic and seismic scattering theory. In this method, a series ... -
Modeling and inversion of seismic data using multiple scattering, renormalization and homotopy methods
Huang, Xingguo (Doctoral thesis, 2020-05-14)Seismic scattering theory plays an important role in seismic forward modeling and is the theoretical foundation for various seismic imaging methods. Full waveform inversion is a powerful technique for obtaining a high-resolution ... -
On the applicability of a renormalized Born series for seismic wave modelling in strongly scattering media
Huang, Xingguo; Jakobsen, Morten; Wu, Ru-Shan (Peer reviewed; Journal article, 2020)Scattering theory is the basis for various seismic modeling and inversion methods. Conventionally, the Born series suffers from an assumption of a weak scattering and may face a convergence problem. We present an application ... -
Traveltime approximation for strongly anisotropic media using the homotopy analysis method
Huang, Xingguo; Greenhalgh, Stewart (Peer reviewed; Journal article, 2019)Traveltime approximation plays an important role in seismic data processing, for example, anisotropic parameter estimation and seismic imaging. By exploiting seismic traveltimes, it is possible to improve the accuracy of ...
