FeSiAl衰减材料在W波段的电磁特性研究

Study on Electromagnetic Properties of FeSiAl Attenuating Material in W-Band

为了研究FeSiAl材料在W波段的衰减性能,利用矢量网络分析仪对涂覆不同厚度衰减材料的标准波导进行了电磁性能测试。测试结果表明,FeSiAl涂层在W波段具有较高的衰减性能,并且衰减量随涂层厚度增加而增大。通过CST微波工作室软件建立了涂覆FeSiAl材料的矩形波导模型,通过试验结果推算出该材料在W波段的电磁参数。

FeSiAl attenuating material was coated inside the straight waveguide,and then the matching and attenuation properties were measured.The measurement result showed that FeSiAl had very good attenuating property,and the attenuation increased with the thickness of coatings increasing.Based on these results,simulation of the straight waveguide with FeSiAl coating inside was carried out by using CST software,and the electromagnetic properties were deduced.
