Abstract
The formalism of the creeping-wave theory has been extended to enable calculations of various incident pulse forms. The particle velocity on the cylinder surface and the pressure radiated to a far-distant observer have been obtained for various pulse shapes. The incident pulse shapes studied are: (1) the delta function, (2) finite modulated step pulse, and (3) finite unmodulated step pulse. The growth curves of particle velocity and pressure have been calculated as a function of a reduced time τ. In addition, the creeping-wave speed and attenuation angle are given for the case of the delta pulse and the finite modulated step pulse.
