Abstract

Recently it has been shown that acoustic Green's functions from sources inside of a medium can be recovered using single-sided reflection data by iteratively solving a Marchenko equation. In recent work, we conjectured how this scheme can be extended in the case of elastic media. In this work, we present a mathematical derivation that validates our previous conjecture, and exemplify it with a numerical example in a solid elastic medium.
