【摘要】：采用终端短路同轴开口波导技术,将开口同轴波导作为传感器,测量样品加载时的复反射系数,运用优化迭代反演求得待测材料的相对介电常数.详细介绍了所采用的理论模型和测量系统,测量了一些常见介质材料的复反射系数,复反射系数参考值与理论计算值基本吻合,证明了该方法的合理性及可行性.
[Abstract]:Using the terminal short circuit coaxial waveguide technology, the open coaxial waveguide is used as the sensor to measure the complex reflection coefficient when the sample is loaded, and the relative dielectric constant of the material to be measured is obtained by optimizing iterative inversion. The theoretical model and measurement system are introduced in detail. The complex reflection coefficients of some common dielectric materials are measured. The reference values of the complex reflection coefficients are in good agreement with the theoretical calculation values, which proves the rationality and feasibility of the method.
