On the alleged breakdown of the Kirchhoff theory in the case of diffraction and interference by a two-dimensional array
P.M. Bronsveld, Bernhard J. Hoenders · Journal of Physics E Scientific Instruments · 1978
The application of a two-dimensional diffraction array to the measurement of wire-cloth screens has been treated by Chapman and Butland (see ibid., vol.10, p.621 (1977)). Here the interference-diffraction pattern of such an array is analyzed in the Kirchhoff approximation according to the Babinet principle. It is shown that the confusion arising from the indistinguishableness of the diffraction patterns of the two complementary arrays does not involve a breakdown in the Kirchhoff theory.
