Abstract
The diffraction of an E-polarized and an H-polarized wave by an imperf ectly conducting slit (on which impedance boundary conditions are impo sed) in an infinite metallic plane is investigated. The two independen t problems are solved by using integral transforms, the Wiener-Hopf te chnique and asymptotic approximations. It is found that the diffracted field consists of the sum of fields produced by the two edges of the planes formed by the slit and a field due to the interaction of the tw o edges.
