Wavefield focusing using a generalised, potentially asymmetric homogeneous Green's function

Marchenko-type integrals typically relate so-called focusing functions and Green's functions via the reflection response measured on the open surface of a volume of interest. Originating from one dimensional inverse scattering theory, the extension to two and three dimensions set in motion various new developments regarding imaging in complex...

Fast evaluation of zero?offset Green's function for layered media with application to ground?penetrating radar

We propose an efficient integration path for the fast evaluation of the three?dimensional spatial?domain Green's function for electromagnetic wave propagation in layered media for the particular case of zero?offset, source?receiver proximal ground?penetrating radar (GPR) applications. The integration path is deformed in the complex plane of the...
