摘　　要：设计分析了一种工作在3~6 GHz内嵌平行板谐振器(PPR)的矩形腔测量系统,给出其几何结构设计方案,在预设观察模式和频点下确定腔体尺寸;采用电磁模拟分析方法,在腔体谐振背景下识别平行板谐振器模式。在此基础上通过品质因数求解获得表面电阻R_s,从而获取高温超导材料的表面电磁特性。将高温超导材料应用于射频乃至更高频段的微波器件中。A test system of a rectangular cavity with a Parallel Plate Resonator(PPR) inside, working between 3 GHz and 6 GHz, is designed and analyzed. Its geometric structure is discussed in detail and its sizes can be determined by three sets of modes and frequencies. In the context of the resonance of the cavity, the mode of the PPR can be identified,the values of Q are obtained as well, and therefore, the microwave surface resistance(R s) can be determined. The electromagnetic characteristics of high-Tcsuperconductive film can be obtained by analyzing the simulation results. The high-Tc superconductive material can be applied to microwave devices in RF and some higher bands.
