: 多分层介质中平面电磁波的传播特性分析 马如慧, 刘生春 ( 7 16000) : 多分层介质中平面电磁波的传播和散射是一个重要研究课 在电磁波正入射, 各区域均由双轴介质组成情 况下, 用代数方法对多分层介质中平面电磁波的传播特性进行分析, 用波阻抗法和等效传输原理计算出了各层介质的反射 系数和透射系数的理论公式结果表明代数方法易于理解但是计算量较大, 波阻抗法计算量降低了一半 : 平面电磁波; 分层介质; 反射系数; 透射系数; 代数方法; 波阻抗 : T N0 11 : A : 1004-373X( 2008) 19-036-03 Analysis of Plane Waves Transmission Rule in Mult-i layered Media MA Ruhui, LIU Sheng hun ( S hool of Physi s and Ele troni Informat ion, Yanan University, Yanan, 716000, China) Abstract: The plane w aves transmission and s attering in mult-i layered media is an important resear h topi . While ele tromagneti w ave is the regional media by the omposit ion of the biax ial, the analysis of plane w aves transmission rule in mult-i layered media by algebrai method is the main on ern of the paper . W orking out ea h layers a ademi expressions of re- fle tion oeffi ient and t ransmission oeffi ient by wave im pedan e method and equivalent t ransmission prin iple. T he results show that algebrai method is easy to understand but a large amount of omputing , w ave impedan e method of redu ing by half.
