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
