Wapenaar, K. and de Ridder, S. orcid.org/0000-0002-0797-7442 (2022) On the relation between the propagator matrix and the Marchenko focusing function. Geophysics, 87 (2). a7-a11. ISSN 0016-8033
Abstract
The propagator matrix "propagates"a full wave field from one depth level to another, accounting for all propagation angles and evanescent waves. The Marchenko focusing function forms the nucleus of data-driven Marchenko redatuming and imaging schemes, accounting for internal multiples. These seemingly different concepts appear to be closely related to each other. With this insight, the strong aspects of the propagator matrix (such as the handling of evanescent waves) can be transferred to the focusing function. Vice-versa, the propagator matrix inherits from the focusing function that it can be retrieved from the reflection response, which reduces its sensitivity to the subsurface model.
