Waveguide channel breakdown due to powerful nanosecond microwave pulses
Abstract
The breakdown of a narrowed waveguide section by powerful microwave pulses at pressures in the range 6,500-100,000 Pa is studied experimentally. The parameters of the pulse were: triangular shape, duration at the base of 100 ns, peak power of 22 MW, and frequency of 2.88 GHz. Pulse repetition frequency was 50 Hz, with frequency stability of the pulse being 0.001. The results lead to the conclusion that in a standard waveguide at atmospheric pressure, pulses of up to 50 MW can be transmitted. Data are compared with other available experimental values.
