| 摘 要： | 为获得直线加速器同轴负载材料FeSiAl的介电常数和磁导率，基于同轴传输反射法，利用矢量网络分析仪，对同轴负载磁性吸波材料FeSiAl的电磁参数进行了测试研究，同时利用电磁场分析软件Microwave Studio进行了测试仿真。研究表明，测量中加工样品与其夹具之间的装配间隙对电磁参数的测试值存在较大影响，进而制作了不同配比的FeSiAl微粉和固体石蜡混合样品，获得混合样品的稳定测试值。对求取电磁参数等效公式的适用性研究表明，Bruggeman，Looyenga，QCACP公式适用于描述该FeSiAl微粉的电磁特性，最后给出了FeSiAl材料的电磁参数。

| Abstract: | It is necessary to obtain permittivity and permeability of microwave-absorbing material FeSiAl.Based upon transmission-reflection method,the complex electromagnetic parameters of FeSiAl were measured by dint of VNA(vector network analyzer).The simulations were done with CST Microwave Studio.Experiments and simulations both indicate that the gap between samples and the test fixture influences the parameter results seriously.Consequently several mixed samples of powdered FeSiAl and paraffin were made with dif... |
