Diffraction of a Normally Incident Plane Wave at a Wedge with Identical Tensor Impedance Faces

Mikhail A. Lyalinov and Ning Yan Zhu, Member, IEEE

Page 914.

Abstract:

Diffraction of a normally incident plane wave by a wedge with identical tensor impedance faces is studied in this paper and an exact solution is obtained by reducing the original problem to two decoupled and already solved ones. A uniform asymptotic solution then follows from the exact one and agrees excellently with numerical results due to the method of parabolic equation.
