Babinet's principle applied to bridged knife edges / by J.H. Whitteker. : Co24-3/7-93-001E-PDF
"In knife-edge diffraction problems, Babinet's principle allows the original arrangement of diffracting screens to be replaced by two new arrangements in which any chosen diffracting screen is absent in one of the new arrangements, and is replaced by its complement in the other. The two new problems may be easier to solve than the original one. The principle is here extended to bridged knife edges, in which the spaces between successive diffracting screens are bridged over by perfectly reflecting plane surfaces that connect the knife edges. Any such structure with a 'valley' can be replaced by other structures that do not have that valley. Again, the new problems may be easier to solve than the original one. This formulation may also be applied to the multiple (unbridged) knife edge problem, whichis a special case of the more general problem"--Abstract.
