Abstract : The authors present in the report efforts to thoroughly understand Babinet's principle for electromagnetic diffraction and the results of the initial efforts to extend the principle beyond its usual range of application. Proof is given that the principle in its present form is invalid for general two dimensional, infinitely thin, perfectly conducting surfaces containing apertures. The only case in which it is valid is the conventional one of an infinite plane. (Author)
