摘要：

The propagation characteristics of a beam generated by driving an aperture with an ultrashort, hence ultrawide-bandwidth, space-time Gaussian pulse are considered. It is shown analytically with an approximate form of the solution that the beam intensity and the beam energy have different diffraction lengths and rates of beam spread in the far field. These beam properties are also discussed for a derivative receiver system. The analytical results are supported with numerical simulations of the exact pulsed-beam solution.
