摘　　要：应用有效介质理论,计算了不同体积比下几种复合吸波剂以及吸波剂与透波体组成的吸波材料的有效电磁参数,并分析了其吸波性能。通过与实验数据的对比,表明这种方法可以很好地预测吸波材料的吸波性能。而且,它可以计算出吸波剂及透波体的最佳配比及材料厚度,这对于设计吸收频带宽、吸收效率高的吸波材料具有一定的参考价值。This paper applied effective media theory to calculate the effective electromagnetic parameters of several composite absorbing agents under different volume ratio and another absorbing material which is mixed by absorbing agent and penetrating agent,and analyzed the absorbing properties.The comparison with experimental data shows that this method can well forecast the absorbing properties of absorbing material.For practical absorbing agent and penetrating agent,this method can compute the optimal proportioning and material thickness,effectively guide people to manufacture high-performance absorbing materials,and it has a certain reference value to design the wide-band high-performance absorbing materials.
