摘　　要：本文研究了电磁波在均匀非磁化等离子体填充的同轴线波导中的传播特性,主要考虑衰减常数与等离子体同轴波导各参数的关系。应用博格尼斯位函数法并结合等离子体特性得到了电磁波传播过程中的衰减常数与相位常数。并对几种特殊情况进行数值分析,计算出衰减常数随等离子体波导各参量的变化曲线。The purpose of this paper is to study the microwave＇s transmission characteristics when it passes in the plasma coaxial waveguide.The relationship between attenuation and the parameters of plasma is mainly considered in the study.By application Borgnis bit function method combined with the plasma characteristics,the attenuation constant and phase constant in the process of electromagnetic wave propagation.
