| 摘 要： | 对求解枝连区域上电磁场问题的投影分解法和快速投影分解法的收敛性进行了分析和比较,并证明了快速投影分解法的收敛速度要快于一般的投影分解法.实际应用表明,快速投影分解法的收敛速度大大加快,其迭代次数大约只有原来的三分之一左右.

| Abstract: | This paper analyzes the convergence of decomposition projective method(DPM) and fast decomposition projective method(FDPM), both of which aim at solving the electromagnetic problems on multi-branch domains. This paper also proves that the convergence rate of FDPM is fast than that of DPM. FDPM's application shows that its convergence rate is very quick. The iterative number of FPDM equals to about one third of the former method. |
