摘要
详细分析了ＴＥ极化波以大角度入射到无金属基底的平面多层吸波结构上时的反射特性，导出连接层间电磁场的通用矩阵公式，计算了两层和三层吸波结构的反射系数，并证明了在何种条件下可以获得低的反射率，在此基础上提出了一个简易设计方法。对进气道和进气道内吸波导流板的两层和三层材料设计都获得了良好的特性。
In this paper,the reflection characteristics of a plane wave of TE polarization incidented with large incident angle on the surface of a multilayer structural absorber without metal base is investigated in detail.A generalized matrix formula is derived to connect the EM fields in adjacent layers.The reflection coefficients of two and three layer absorbers are evaluated.The conditions under which the low reflectances may be achieved are investigated.Based on these analysis,an easy handled design method is presented.Design examples of two and three layer structural absorbers for inlet and absorbing quide plate in inlet all give good performances.
