空气和SF6气体击穿对微波传输的影响
Effect of air and SF6 breakdown on transmission of high power microwave
摘要
通过喇叭有效口径渐变法进行了L波段、脉宽30 ns的高功率微波空气以及SF6气体击穿实验, 给出了实验中得到的典型波形, 分析了空气以及SF6气体击穿对微波传输的影响。实验表明:空气击穿产生等离子体对微波传输的影响主要表现为对微波功率的反射, 使微波脉宽变窄, 而SF6击穿则主要体现为对微波功率的吸收, 使峰值功率降低。
Abstract
By means of changing the effective aperture of horn antenna, the experiment of air and SF6 microwave breakdown is carried out for L-band microwave with pulse duration being 30 ns. The microwave breakdown waveforms are derived, and the effect of air and SF6 breakdown on the transmission of high power microwave is analyzed. The experiment shows that, air breakdown mainly shortens the pulse width of high power microwave, while SF6 breakdown mainly reduces the peak power of high power microwave.
