提出了一种利用截止圆波导法测量毫米波低损耗介质板的简便方法。利用基于Ritz-Galerkin方法的严格分析计算出的校正图解，可以简单地校正条纹效应。用该方法对一些低损耗介质板进行了测量，以寻找适合毫米波应用的材料。结果表明，改性聚烯烃具有优良的电性能，r=2.31，tan=1.3×10~(-4)，与聚四氟乙烯相近。
An easy-to-treatment technique is proposed to measure low-loss dielectric plates by a cut-off circular waveguide method in millimeter wave region. The fringe effect can be corrected simply using correction charts calculated from the rigorous analysis based on Ritz-Galerkin method. Some low-loss dielectric plates were measured by this method to find out proper material for millimeter wave applications. It is found that modified polyolefin has an excellent electric characteristic of¿r=2.31 and tan ¿=1.3×10¿4, which is similar to PTFE.
