基于Maxwell方程的一阶状态矢量微分方程描述 ,本文导出了均匀平面波入射下任意吸波材料层反射和透射系数的统一表述 ,分析了反射和透射系数随媒质参数、材料厚度、入射角度的变化规律 ,并从另一角度对有耗材料参数Lindell条件的必要性进行了验证 ,得到了一些有益的结论 。

Based on a first order state vector differential equation representation of Ma xwell’s equations, the general analytical formulas are derived for reflection c oefficient and transmission coefficient of an arbitrary wave absorbing layer, s uch as isotropy, uniaxial anisotropy and uniaxial chirality wave absorbing mate rial. The medium lossy conditions are also discussed, and some useful conclusion s are obtained. This work may provide the theoretical preparation for the recons truction of media parameters for arbitrary wave absorbing material.
