Diffraction by a right-angled impedance wedge

A plane electromagnetic wave is incident at an oblique (skew) angle on a wedge of open angle 3π/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 pre...
