We introduce a time-perturbation scattering theory for the time reflection and refraction of waves and show the application of the methods to inverse scattering theory. Topics include time-dependent Schro¨ dinger equation, electromagnetic, acoustic inverse scattering theory. Numerical solutions in which time-perturbation wave equations are discretized in time and space by the finite difference method provide solutions of time-perturbation wave equation. The solutions show the connection between the time-perturbation inverse scattering problem and the acoustic wave equation inverse scattering problems.Note: This paper was accepted into the Technical Program but was not presented at IMAGE 2022 in Houston, Texas.Keywords: wave scattering, numerical solutions, inverse scattering problemsPermalink: https://doi.org/10.1190/image2022-3740290.1FiguresReferencesRelatedDetails Second International Meeting for Applied Geoscience & EnergyISSN (print):1052-3812 ISSN (online):1949-4645Copyright: 2022 Pages: 3694 publication data© 2022 Published in electronic format with permission by the Society of Exploration Geophysicists and the American Association of Petroleum GeologistsPublisher:Society of Exploration Geophysicists HistoryPublished Online: 15 Aug 2022 CITATION INFORMATION Xingguo Huang, Ru-Shan Wu, Pan Zhang, Wenrui Ye, and Morten Jakobsen, (2022), "Inverse scattering theory: Time-dependent perturbation theory for wave scattering in time varying media," SEG Technical Program Expanded Abstracts : 3146-3150. https://doi.org/10.1190/image2022-3740290.1 Plain-Language Summary Keywordswave scatteringnumerical solutionsinverse scattering problemsPDF DownloadLoading ...
