摘要: 圆柱型同轴谐振腔中的横磁模TMs10的电场分量沿圆周方向呈周期性均匀分布，电感调谐的圆柱型谐振腔的圆周边界不再规则，腔内场分布的均匀性遭到破坏。为了能准确描述场分布的情况，该文建立了不规则圆周边界的同轴谐振腔的物理模型，通过理论分析得出了边界发生变化时同轴谐振腔中电场分布的变化规律。并通过三维电磁场软件进行了数值模拟，模拟结果与理论分析所得结论一致。Abstract: The electric field component of TM310 mode in cylindrical coaxial resonator presents periodic distribution along with circumference, the cylindrical resonator circumference borders with tunable inductors is irregularity and uniformity of the distribution is destruction. In order to accurately describe the distribution situation, in the paper, a irregular circumference border coaxial resonator physical model is established. The formula of the electric field distribution through CST and the numerical simulation, simulation results with theoretical analysis concluded unanimously.
