Abstract :
In this paper, we present a computationally efficient and physically appealing discretized Gabor-based parameterization, in terms of narrow-waisted ray-like pulsed Gaussian beams, for the three-dimensional (3D) vector electromagnetic fields radiated from short-pulsed arbitrarily polarized large 2D truncated aperture distributions. This analysis extends the time-harmonic results in Maciel and Felsen (2000) to the time domain (TD), following the guidelines of our previous investigation of pulsed radiation of 2D fields from 1D large truncated apertures (Galdi et al. 2000).
