Figure 2
Two-level forward scattering approximation using the T-matrix approach with an incident plane wave propagating upwards. The third column represents scattering from the top scatterer, located at distance kd from the bottom scatterer. By neglecting backscattering, this can be approximated by the sum of (i) the kinematic scattering of the incident plane wave by the top scatterer (first column) and (ii) the secondary scattering following kinematic scattering from the bottom scatterer (second column). The scattering from the bottom scatterer is viewed by the top scatterer as a particular incident wave (neither planar nor spherical) emitted from a point source at a distance kd.
