摘　　要：提出了适合一类特殊区域上电磁场问题的算法 ,依照区域几何形状将大问题分解成几个小问题求解 ,其收敛速度是几何的 .将其应用于开槽慢波管的反射系数和相位的分析 ,得出了影响上述参量的主要因素 。An algorithm is presented for solving electromagnetic problems in special domains with many branches. According to the geometric shape of domains the large matrix is divided into several small ones. The convergence rate of iterative solution is geometrical. The method is applied to the reflecting parameter and phase analysis of the slotting slow wave guide. Then we find the main factors of affecting the above parameter and phase, finally give them the relation curves.
