Abstract

The space - time acoustic wave diffraction due to a spherical Gaussian pulse near an absorbing half plane introducing the Kutta - Joukowski condition (wake condition) is considered. The temporal Fourier transform is used to calculate the diffracted field. 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.
