A plane electromagnetic wave is incident at an oblique (skew) angle on a wedge of open angle 3 π /2 with scalar face impedances, the same on both faces. When the theory previously developed for wedges of arbitrary angle with tensor face impedances is specialized to this case, the analysis simplifies, and the resulting expressions for the geometrical optics, surface wave and diffracted fields are presented. Because of the practical importance of this geometry, a large set of figures is included showing the behavior of the diffracted field for a variety of face impedances.
