An Approximate UTD Ray Solution for Skew Incidence Diffraction by Material Coated Wedges of Arbitrary Angle

This paper presents a new approximate uniform geometrical theory of diffraction (UTD) coefficient for a coated wedge as in Fig. 1. As is well known, skew incidence [1] wedge diffraction coefficient are available for the half plane (coated [1] and materials half-plane [2]), full plane and right angle wedges. But for general interior impedance or coated wedge angles at skew incidence only approximations are available. One such approximate solution was propose
