| 摘 要： | 基于正切网络法,将填充低耗介质的波导段等效为正切网络,利用曲线拟合法求得网络参数,从而反演出相对介电常数。借助于微波CAT(Computer Aided Test)系统,对实际低耗电介质材料进行了测试,测量结果与标称值吻合较好。

| Abstract: | On the basis of the tangent network method,the waveguide unit filled with low-loss dielectric was identified with the tangent network,and the curve fitting method was used to work out network parameters,then the dielectric constant was derived.With microwave CAT(Computer Aided Test)system,the actual low-loss dielectric was measured,and the results agree well with the nominal value. |
