提出了一种利用截止圆波导反射法测量液体介电性能的方法，可以在不使用短端的情况下，从三种参考材料中估算未知材料的介电性质。此外，实验还发现，即使将观测平面移到振荡器一侧的SOL标定面上，也可以准确地确定液体材料的复介电常数。最后，数值验证了该方法可以在很宽的材料常数范围内估计液体介电常数，而不需要以短路终止为标准。
A procedure for estimating the dielectric properties for unknown materials from three reference materials without using a short termination was developed for dielectric measurement of liquids via the cut-off circular waveguide reflection method. Moreover, it was also found that the complex permittivity of liquid material could be correctly determined even when the observation plane was moved to the SOL calibration plane on the oscillator side. Finally, it was numerically verified that liquid dielectric constant can be estimated within a wide range of material constants without using a short termination as a standard in the proposed method.
