Abstract
A new method of generating ultra-wide-band electromagnetic pulses usin g a Tl2Ba2CaCu2O8 high T(c) superconductor as a fast laser activated o pening switch is presented. The superconductor is used as an opening s witch with a current charged transmission line pulse forming network t o produce jitter-free triggered square pulses which are radiated by an ultra-wide-band conical antenna. We report radiation and reception of pulses with center frequencies near 3.5 GHz and a bandwidth in excess of 80%. We also discuss how this technique can be used to assess vari ous wide-band antenna designs.
