It may be simplified in the following two (opposite) limits. (i) Fraunhofer diffraction takes place when z / a > > a / λ – the relation which may be rewritten either as a < < (zλ)1 / 2, or as ka2 < < z. In this limit, the ratio kx, 2 / z is negligibly small for all values of x′ under the integral, and we can approximate it as.

6.3: Angular Spectrum Method

6.3: Angular Spectrum Method. Our goal is to derive the field in some point (x, y, z) with z = 0, given the field in the plane z = 0, as is illustrated in Figure 6.3.1. The sources of the field are assumed to be in the half space z < 0. One way to see how light propagates from one plane to another is by using the angular spectrum method.
