摘　　要：从电磁场有限元法出发,采用有限元撕裂对接法将大型复杂模型转化为若干个小型简单模型来进行分析,引入高阶传输条件和并行计算策略进一步提升了有限元撕裂对接法的性能。对基片集成波导和微带滤波器两种典型微波无源器件的S参数进行了仿真分析,数值结果表明了方法的正确性和有效性。Based on the finite element method （FEM） in electromagnetism, a finite element tearing and interconnecting （FETI） method was adopted to transform a large-scale complex model into several small-scale simple models for the analysis. High order transmission condition and parallel computing strategy were introduced to further improve the performance of the FETI method.S parameters of two typical microwave passive devices including substrate integrated waveguide （SIW） and microstrip filter were simulated and analyzed. The numerical results demonstrate the accuracy and efficiency of the proposed method.
