Generalized screen propagators (GSP) can be considered to be super-wide-angle one-way propagators with implementation in dual domains,which neglect reverberations between heterogeneities but correctly handle the forward multiple-scattering,including focusing/defocusing,diffraction,refraction and interference of waves.
