提出了一种新型的圆柱形谐振腔结构，用于截止波导法，以分别抑制轴向TE模和径向TM模。此外，通过使用七个铜腔和三个低损耗介质板进行循环测试。数值计算和实验验证了这种新型结构的谐振腔对抑制不需要的谐振模是有效的。此外，它被发现，这种方法的测量精度估计在1%以内的<$r和15分之一的tan <$。
A novel structure of a circular cylindrical resonator for the cut-off waveguide method are proposed to suppress unwanted TE modes in the axial direction and TM modes in the radial direction, respectively. Moreover, the round robin test is performed by using seven copper cavities and three low loss dielectric plates. It is verified numerically and experimentally that the novel structure of the resonator is useful to suppress the unwanted resonance modes. Moreover, it is found that the measurement accuracies of this method are estimated within 1 percent for ¿r and within 15 percents for tan¿.
