摘要
对水泥基掺杂混合吸波剂复合材料的吸收性能进行了研究，在水泥基体中分别填充不同比例的炭黑／二氧化锰、炭黑，铁粉、炭黑／铁氧体并进行吸波性能测试，结果表明试样在2．6～18GHz频段内具有更强的吸收性能，〉10dB的带宽最多可达12．4GHz。并用阻抗匹配和谐振理论解释了吸波剂含量和种类对吸收性能及吸收峰的影响。
The absorbing property of cement-based composites filled with mixed absorbents was studied. The absorbing property of the cement composites filled with carbon black（CB）/manganese dioxide, CB/iron powder, CB/ferrite in different scales was tested and the result showed that the samples have more better absorbency which bandwidth excelling 10dB reached 12.4 GHz at best in 2.6-18 GHz. The impedance matching and resonance theories are used to explain how the contents and classes of absorbents affect the absorbing property and the value of absorbing peak.
