Large current radiator with S-diode switch

A large-current radiator (LCR) for the radiation of nonsinusoidal electromagnetic (EM) pulses with duration in the nanosecond range was developed. The time variation of the radiated electric field strength resembles one period of a sinusoid with the peak amplitude of the first half cycle being 1.2 times as large as the peak amplitude of the second half cycle. The duration of the first half cycle measured at one half the peak amplitude is 1 ns while the duration of the whole signal is 3.5 ns. The peak amplitude of the electric field strength at a distance of 3 m from the radiator is 56 V/m.
