On the Skew Incidence Diffraction by an Impedance Wedge with Arbitrary Face Impedances

ABSTRACT

New diffraction coefficients are derived for an impedance wedge at skew incidence. These are based on the solution of a new set of difference equations, yielding a single expression which recovers ail known skew incidence impedance wedge diffraction coefficients. An. important aspect of the derived expression is that a single computer code can be written for all wedge angles (with arbitrary face impedances) for which an exact solution is possible and furthermore it opens the possibility of deriving approximate solutions for other wedge angles.
