| 摘 要： | 基于气体极化强度叠加模型,推导了混合气体的介电常数，得到了高功率微波在混合气体中传播时的折射指数和衰减系数。研究发现，高功率微波大气电离产生的混合气体是快速时变的色散有耗介质。根据其色散性分析了微波在混合气体中的传播速度以及微波脉冲在其中的展宽效应，同时，根据其有耗性对微波脉冲在混合气体中传播时的缩短效应进行了研究。研究结果均能自洽地过渡到对流层或电离层电波传播理论。

| Abstract: | The propagation characteristic in mixture atmosphere of high power microwave is presented based on atmosphere polarization intensity superposition. By deducing dielectric constant of mixture atmosphere, the refractive index and attenuation coefficient of high power microwave propagation in mixture atmosphere are obtained. It can be found through research that the mixture atmosphere is a quick changed dispersing and lossy medium. The microwave pulse widen effect and propagation veloctiy induced by the dispersion characteristics of mixture atmosphere are researched, and the pulse shorten effect induced by the lossy characteristics of mixture atmosphere is analyzed. All the conclusions is self-consistent developed to the propagation theory of troposphere or ionosphere. |
