摘　　要：介绍了材料电磁参数发生变化时,样品微波反射率的变化。结果表明,真正决定样品散射行为的是样品的输入阻抗,而不是特征阻抗,样品的反射率随其电磁参数呈振荡起伏的关系,而且这种关系因样品而异,并不存在单一的趋势性变化。The dependence of diffraction property of microwave absorbing samples on the composing materials＇ electromagnetic parameters was systematically analyzed. According to the analysis, it is the input impedance, rather than characteristic impedance, that determines the sample diffraction behavior. The dependence of sample input impedance on the material electromagnetic parameters is complicated and oscillatory, and the dependence varies for different samples. No single tendency exists in this relation.
