Radiation of a sequence of high-power S-band microwave pulses by a system of two gyromagnetic lines with saturated ferrite in a scheme with repeated use of a high-voltage pulse

Abstract

The results of the development of a microwave oscillation generation technology using gyromagnetic lines with saturated ferrite are presented. A sequence of two pulses of microwave oscillation of different frequencies in the S‑band is radiated into an open space using two nonlinear transmission lines with saturated ferrite connected in series and excited by a single high-voltage pulse. The central conductors of the lines represent corrugated structures with periodically arranged rings of magnets and ferrites. The pulses are radiated by various types of broadband antennas. It is shown that for the effective emission of microwave oscillations excited by such a structure, a magnetic electric dipole will be an optimal radiating antenna choice. The repetition rate of the pulses emitted with this dipole is found to be 20 MHz.
