Propagation characteristic of high power microwave in mixture atmosphere based on polarization superposition model

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.
