结构偏心对开放式同轴谐振腔性能的影响
Effects of structural misalignments on open coaxial resonator performance

摘要: 采用CST微波工作室软件，数值模拟了内外导体轴线偏心对开放式同轴谐振腔的影响。结果表明：不管是内外导体的轴线发生平行偏心，还是倾斜偏心，都引起开放式同轴谐振腔的谐振频率、品质因数和场振幅实质性下降；其中，倾斜偏心产生的影响比平行偏心更为严重。Abstract: The effects of the misalignment between the inner-rod axis and the outer-wall axis in an open coaxial resonator are simulated by using the software CST microwave studio. The calculated results show that either the parallel misalignment or the oblique misalignment between the inner-rod axis and the outer-wall axis causes substantial decrease of the resonant frequency, the Q-factor, and the field amplitude of the open coaxial resonator; and generally, an oblique misalignment has more adverse influence than a parallel misalignment.
