Singularity expansion method formulation for impulse response of a perfectly conducting thick cylinder
Abstract
The impulse response of an infinite, perfectly conducting thick cylinder to normally incident, transversely polarized, impulsive plane wave illumination is determined. Spectraldomain analysis based upon the singularity expansion method reveals that this response consists of a discrete series of natural resonance modes (natural frequencies are computed) augmented by a series of continuousspectrum terms. The resultant latetime response demonstrates the correct "creeping wave" behavior as predicted by the Fourier synthesis technique, but with far fewer terms required for convergence.
