摘要：

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. (C) 1998 Elsevier Science Ltd.
