WebOct 6, 2010 · There's far-field limit r>D^2/lambda which is discussed in optics too and is derived from Green function aproximation (expansion in series, you know..) in Rayleigh-Sommerfeld diffraction formula (similar to our vector potential as I suppose). What about connection between optics and elmag. point of view? Eirp WebRayleigh-Sommerfeld modelling, when applied using a forward Born approximation, is shown to be the familiar phase-shift migration running in reverse. Compared to the Kirchhoff method, Rayleigh-Sommerfeld is much faster, especially on large datasets, but produces a similar response. Rayleigh-Sommerfeld is used to create an exhaustive 3D synthetic
