Acoustic diffraction near a penetrable strip

The diffraction of an acoustic wave by a penetrable strip introducing the Kutta-Joukowski condition is investigated. Mathematical problem which is solved is an approximate model for a noise barrier which is not perfectly rigid and therefore transmits sound. The problem is solved using integral transforms, the Wiener-Hopf technique and asymptotic methods. It is found that the field produced by the Kutta-Joukowski condition will be substantially in excess of that in its absence when the source is near the edge. Finally, physical interpretation of the result is discussed.
