Faculty Civil Engineering and Geosciences Department Geotechnology Date 2006-12-04 Abstract It has been shown by many authors that the cross correlation of two recordings of a diffuse wave field at different receivers yields the Green’s function between these receivers. Recently the theory has been extended for situations where time-reversal invariance does not hold (e.g., in attenuating media) and where source-receiver reciprocity breaks down (in moving fluids). Here we present a unified theory for Green’s function retrieval that captures all these situations and, because of the unified form, readily extends to more complex situations, such as electrokinetic Green’s function retrieval in poroelastic or piezoelectric media. The unified theory has a wide range of applications in ‘‘remote sensing without a source.’’ To reference this document use: http://resolver.tudelft.nl/uuid:5857194a-8e97-4b28-aaee-e77953dfc4bc DOI https://doi.org/10.1103/PhysRevLett.97.234301 Publisher American Physical Society ISSN 1079-7114 Source Physical Review Letters, 97 (23), 2006 Part of collection Institutional Repository Document type journal article Rights (c) 2006 The Author(s); American Physical Society Files PDF Wapenaar_2006.pdf 109.68 KB Close viewer /islandora/object/uuid:5857194a-8e97-4b28-aaee-e77953dfc4bc/datastream/OBJ/view
