摘要/Abstract

摘要：

采用模匹配法对一种陶瓷介质填充的圆柱谐振腔TE₀₁₁、TE₁₁₁模的谐振特性进行了理论分析和软件仿真. 计算了该种谐振腔的谐振频率，并与其他理论方法得到的仿真结果进行了比较，验证了理论方法的正确性. 在此基础上，分析了陶瓷介质尺寸对谐振频率的影响. 与目前铷钟广泛使用的微波腔相比，该种谐振腔腔体的体积在很大程度上得到减小，这对于铷原子钟小型化的实现具有重要的作用.

关键词: 新型小铷钟, 圆柱形谐振腔, 模匹配法, 谐振特性

Abstract:

The mode matching method was used to analyze the resonant characteristics of TE₀₁₁ and TE₁₁₁ modes of a cylindrical resonant cavity loaded with ceramics material. The cavity is of smaller volume than those commonly used, and can be utilized in miniaturized rubidium atomic clocks. By calculating the resonant frequency of the cavity and comparing the result with that calculated with the commercial software, the correctness of the method was verified. In addition, the effects of the dimension of ceramics material on the resonant frequency were analyzed.

Key words: miniaturized rubidium atomic clock, cylindrical resonant cavity, mode matching method, resonant characteristic
