Acoustic diffraction by an impedance wedge

ABSTRACT.  We consider the boundary-value problem for the Helmholtz 
equation connected with an infinite wedge with an impedance boundary on 
its face. The scheme of solution includes applying the Kontorovich-Lebedev 
(KL) transform, derivation of an integral equation satisfied by the KL spectral amplitude and obtaining near and far field representations together with the conditions of validity of these representations.
