摘　　要：用不对称传输线模型分析了平面电磁波垂直入射于多层双各向同性媒质的反射和透射问题 ,导出了形式上较简单的计算多层双各向同性媒质界面反射和透射系数公式。为了便于和已有的文献结果相比较 ,给出计算实例 ,结果表明 ,用此公式得出的结果和文献结果一致 ,为计算多层双各向同性媒质的反射和透射带来方便 ;同时 ,对双各向同性媒质 。The problem of reflection and transmission of electromagnetic wave through multi-layer bi-isotropic media is analyzed by nonsymmetric transmission-line model. The formula of reflection and transmission coefficients is deduced. To compare with the results in previous literatures, some numeral examples are presented. The comparison shows that our result accords with that of literatures. It is convenient for calculating the reflection and transmission of electromagnetic wave through multi-layer bi-isotropic media. At the same time, both the changes in nonreciprocal and chiral parameters have larger effects on reflection and transmission coefficients.
