WebWe benchmark wavefields, which are computed in several 3D large-scale subsurface models with a sparse multifrontal direct solver and the nonadaptive/adaptive stencils, against analytical solutions when available and the highly accurate discretization-free convergent Born series method. WebHere, as an application of the method we develop to analyze the Born series, we obtain a su cient condition for convergence of the inverse Born series. This paper is organized as follows. In Section 2, the proof of Theorem 1 on the convergence of the Born series is presented. In Section 3 we discuss the convergence of the inverse Born series for

On convergence of Born series - University of Pennsylvania

WebA convergent Born series (CBS) was proposed by Kleinman et al. based on a generalised overrelaxation method [2, 3]. More recently, Osnabrugge et al. introduced another CBS through the use of a preconditioner based on the scattering potential [4], which has since found many applications [5, 6, 7, 8]. WebA simple iterative solution is the Born series, but it is only convergent when the scattering potential is sufficiently small. In this study, we have used the so‐called homotopy analysis method to derive an iterative solution for the vectorial Lippmann–Schwinger equation which can be made convergent even in strongly scattering media. The ...
