| Popis: | Directive pulsed fields with steep rise times are remarkably nondispersive in space and time and thus invite diverse uses in optics as well as microwaves (energy transfer, target identification, clutter penetration). Recent investigations of these pulses have shown the aptness of spectral representations other than conventional time-harmonic Fourier transforms, prinicpally Heyman and Felsen’s transient plane waves1 and J. Brittingham’s "focus” wave modes.2 |
