(TU Delft Applied Geophysics and Petrophysics) Date 2016 Abstract Single-sided Marchenko equations for Green’s function construction and imaging relate the measured reflection response of a lossless heterogeneous medium to an acoustic wave field inside this medium. I derive two sets of single-sided Marchenko equations for the same purpose, each in a heterogeneous medium, with one medium being dissipative and the other a corresponding medium with negative dissipation. Double-sided scattering data of the dissipative medium are required as input to compute the surface reflection response in the corresponding medium with negative dissipation. I show that each set of single-sided Marchenko equations leads to Green’s functions with a virtual receiver inside the medium: one exists inside the dissipative medium and one in the medium with negative dissipation. This forms the basis of imaging inside a dissipative heterogeneous medium. I relate the Green’s functions to the reflection response inside each medium, from which the image can be constructed. I illustrate the method with a one-dimensional example that shows the image quality. The method has a potentially wide range of imaging applications where the material under test is accessible from two sides To reference this document use: http://resolver.tudelft.nl/uuid:c5c95c5b-cf7d-48db-b378-b33d40fd8915 DOI https://doi.org/10.1103/PhysRevLett.116.164301 ISSN 0031-9007 Source Physical Review Letters, 116 (16), 1-6 Part of collection Institutional Repository Document type journal article Rights © 2016 E.C.
