摘要
将形状不规则的同轴线型加速器谐振腔等效成微波电路,再利用常数单元边界元法求解二维电磁场的边值问题,以提取等效电路参数。由等效微波电路可求得谐振频率。应用这种方法对30MeV加速器谐振腔的谐振频率进行了数值分析,所得结果与实验结果吻合良好。
The intricate coaxial line resonance cavity is converted to equivalent microwave circuit, then the constant boundary element method is used to extract the equivalent circuit parameter by solving a two-dimensional electromagnetic fields. After that, the resonant frequency of the coaxial line resonance cavity is analyzed. Numerical results are in good agreement with those measured.
