A preliminary study of a novel approximate UTD ray solution of an oblique EM diffraction by an impedance discontinuity in a planar surface

This paper presents a preliminary study of a novel approximate UTD ray solution of an oblique electromagnetic (EM) diffraction by an impedance discontinuity in a planar surface. The proposed solution is heuristically obtained from the Weiner-Hopf (W-H) solution. This leads the proposed solution relatively simple and closed form expression which is suitable for engineering applications. The comparison between the proposed solution and the W-H solution also preformed and shows good agreement for all the co and cross-polarizations.
