Abstract :
We study the arrival times of a transient creeping wave (CW) and a transient whispering-gallery mode (WG) when a pulse wave is incident on one of the edges of a cylindrically curved conducting open sheet. The time-domain asymptotic solutions for the transient CW and the transient WG are derived asymptotically by applying the Fourier transform method. We show the interesting phenomenon that the transient CW propagates along the curved sheet later than the transient WG.
