90 kV 1800 A 85 ps rise time electromagnetic shockline for UWB applications

Abstract

A ferrite-loaded coaxial line has been developed for operation with axial magnetic field bias, at a 100 kV input pulse voltage. Output rise times of 85 ps are obtained at 90 kV into a 50 Ω load. These results confirm that rapid shock wave switching based on the stimulation of damped gyromagnetic precession can be effectively exploited in relatively large diameter ferrite beads as a means of obtaining < 100 ps rise times at high pulse voltages.
