WebIn this section, we recast Kirchhoff’s diffraction formula in a form that uses a Dirich-let Green’s function (i.e., one that vanishes on the boundary surface) and obtain the Rayleigh-Sommerfeld diffraction formula. In the next section, we show that this re-formulation is equivalent to the plane-wave spectrum approach to diffraction, and use eac local leadership council
