The imaginary part of the scattering Green function: monochromatic relations to the real part and uniqueness results for inverse problems
Alexey Agaltsov, Thorsten Hohage, Roman Novikov
For many wave propagation problems with random sources it has been demonstrated that cross correlations of wave fields are proportional to the imaginary part of the Green function…
