## Scattering of X-Waves from a Circular Disk Using a Time Domain Incremental Theory of DiffractionBy A. M. Attiya, E. El-Diwany, A. M. Shaarawi, and I. M. Besieris
Abstract:
The diffraction and scattering of a first-order ultrawideband TE X-wave by a perfectly conducting circular disk is investigated using an augmented time-domain incremental theory of diffraction. The analysis relies on a pulsed plane wave representation of the incident X-wave. The diffraction and scattering of each constituent pulsed plane wave component is calculated at the observation point. A subsequent azimuthal angular superposition yields the diffracted and scattered field due to the incident X-wave pulse. Making use of the localization and symmetry properties of the incident TE X-wave, a novel four-sensor correlated detection scheme is introduced which is particularly effective in detecting the edges of the scattering disk and has an exceptional resolving power.
