Abstract

The results of the breakdown of microwave pulses in air have been described in this paper. The experimental study has been done in a waveguide, with the frequency of 9.37 GHz, and the peak power up to 200 kW, pulse width from 0.3 microsecond(s) to 2.0 microsecond(s) , single shot and repetition rate up to 970 Hz, and the processes of the breakdown of repetitive pulse were also recorded for ten pulses. The analytic methods for threshold power density are presented also. The comparisons between the theoretical and the experimental results for the breakdown threshold are presented, and in good agreement.
