Diffraction by a Slit Aperture Formed by Two Inclined Surfaces

Abstract

The problem of diffraction by a slit aperture in a nonplanar screen formed by two inclined half� planes is formulated in terms of integral equations by means of the Lebedev transform. A convenient iterative solution of these equations is presented, based on a theorem by Karp and Zitron and its interpretations. The diffracted field is computed and compared with experimental measurements, and is found to contain a reflection interaction effect due to the nonplanar screen geometry.
