Fe基玻璃包覆微丝的吸波性能研究

Study on microwave absorption properties of glass-coated Fe-rich microwires

实验分析了微丝的组织结构，表明微丝是非晶态的，内部芯丝表面光滑，在长度方向上厚度均匀。用矢量网络分析仪测定了微丝的电磁参数，并进行了不同填充率不同厚度的单层吸波涂层设计，结果显示微丝在微波波段10～18GHz频段范围内具有较好的衰减特性，反射率最小值为--32dB，吸波效果好。

The study of the microstructure of Fe-rich glass-coated microwires were conducted. The microwave electromagnetic parameters were measured by microwave vector network analyzer. The results show that the microwires is amorphous. Microwires have high absorption ability on high frequency bands of 10-18GHz, and the smallest reflectivity is R= - 32dB.
