a network analyzer system is used to make frequency-swept s-parameter measurements on the loaded stripline fixture from which complex permittivity and complex permeability may be calculated.
以带线系统为测试夹具,利用网络分析仪在微波频率下测量材料的复介电常数和复磁导率。
it also showed that the complex dielectric constant and complex permeability decrease as the measuring frequency increasing, and maximum dielectric loss was 0.30, but magnetic loss is small.
其介电常数、磁导率基本都随测试频率的增加而下降;介电损耗值最大可达到0.30,磁损耗值较小。
the absorbent was analysed by sem and xrd and the magnetic alloy powder-paraffin sample was made a complex permeability measurement in the radar frequency.
