The proposed method is referred to as the cross-correlated CSI. It\nenables better robustness and higher inversion accuracy than both the classical\nCSI and multiplicative regularized CSI (MR-CSI). In addition, we show how the\ngradient of the modified cost functional can be calculated without\nsignificantly increasing the computational burden. The advantages of the\nproposed algorithms are demonstrated using a 2-D benchmark problem excited by a\ntransverse magnetic wave as well as a transverse electric wave, respectively,\nin comparison to classical CSI and MR-CSI.","url_abs":"http://arxiv.org/abs/1906.10864v1","url_pdf":"http://arxiv.org/pdf/1906.10864v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"cross-correlated-contrast-source-inversion","repo_url":"https://github.com/TUDsun/CC-CSI","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
