POINT SOURCE DIFFRACTION BY
AN ABSORBING STRIP IN A MOVING FLUID
S. ASGHAR, TASAWAR HAYAT AND M. AYUB

Abstract. The scattering of an acoustic wave by a strip in the presence of a moving fluid due to a point source is studied. The problem is solved by using integral transforms, the Wiener-Hopf technique and asymptotic methods. The diffracted field from the two edges of the strip and a field due to the interaction of the two edges are obtained. The physical interpretation of the results is then discussed
