摘要
高功率微波的强电场与大气作用使空气电离,中性分子的电离频率与等效电场强度、大气压强密切相关。在一个较宽的范围内研究电子与大气中性分子的相互作用,分析讨论了高功率微波传输一个脉冲后电子浓度和折射率随微波有效电场强度的变化。
The intense field of high power microwave causes ionization of neutral particle in atmosphere and the plasma comes into being. The ionization frequency of neutral particle relates to electric field intensity and atmospheric pressure. This paper presents the interaction between electron and air neutral molecules in comparatively wide region. When an impulse of high power microwave is propagated, the variation of electron concentration and refractive index accompanying with that of effective electric-field also intensity is also introduced.
