摘要
作者提出的自适应共轭梯度方法是对共轭梯度方法的改进和完善.本文将自适应共轭梯度方法用作多重网格方法的光滑迭代构造了多层自适应共轭梯度方法,对介质加载波导和屏蔽微带线的数值分析表明,多层自适应共轭梯度方法是求解电磁问题十分有效的快速迭代方法.
Adaptive conjugate gradient method proposed by the authors is an improvement and a complement to the conjugate gradient method. In this paper, the adaptive conjugate gradient method is applied to the smoothing iteration of multigrid method to construct multilevel adaptive conjugate gradient method. Numerical analysis for dielectric loaded waveguide and shielded mi-crostrip line illustrate that the multilevel adaptive conjugate gradient method is a powerful iterative method in solving electromagnetic problems.
