Summary form only given. New method of high voltage power transformation into high frequency oscillations in the coaxial line with temporal dispersion is investigated. Temporal dispersion is due to pulsed magnetization switching of initially saturated with axial bias field ferrite. Pulsed magnetic field is created by high voltage nanosecond pulse propagating through the nonlinear transmission line...
The paper presents the results of recent experiments on the generation of subgigawatt RF pulses using two types of nonlinear transmission lines (NLTL's). In the high-voltage coaxial lines, we used: (1) periodic gas gap structure and (2) uniformly loaded saturated ferrite with axial bias. The concept of the first element is based on the in-phase composition of RF fields produced by currents in the...
In this paper, Ni-Zn ferrite loaded coaxial line, using oil as insulation, with subnanosecond rise time at the input pulse voltage up to 360 kV into a 50 load is described. The dependence of the shock front development on the line length and pulse voltage was investigated. The experimental data were compared with analytical predictions of early theory. The experimental and expected results are shown...
Results of research aimed at stabilizing microwave radiation parameters in the pulse-periodic mode of relativistic BWO nonstationary generation are discussed. The possibility of electromagnetic oscillation phase fixation within the microwave pulse, as well as of minimization of peak power spread from pulse to pulse is shown.
