摘要
介绍了一种基于多状态技术的材料电磁参数测量系统的原理 ,重点说明了四态四端口反射计 ,同时提出了一种利用二端口网络变换系数确定材料电磁参数的方法。给出了在 X波段对部分材料测量的实验结果。系统简单、精度高且易于实现。
A setup for measuring the electromagnetic parameters of linear materials based on multi-state techniques is described with emphasis on a four-state and four-port reflectometer. A method for determining the electromagnetic parameters of materials is also presented by using the transformation coefficients of a two-port network. In addition, the experimental results of measuring materials at X-band are given. Simplicity, high accuracy and easy realization characterize the setup.
