论文提出了一种叠层矩量法分析多尺度目标电磁特性。论文采用矩量法直接计算强相互作用区域,多层矩阵压缩方法(MLMCM)和多层快速多极子方法(MLFMA)分别用于加速计算低频和高频作用区域。论文通过使用多分辨ILU(MR-ILU)预条件加速迭代求解矩量法离散多尺度目标产生的病态矩阵方程。通过分析实际多尺度目标电磁特性证明论文方法的有效性。
The paper presents a method of stacking moments to analyze electromagnetic characteristics of multi-scale targets. The paper uses the method of moment to directly calculate the strong interaction area. MLMCM and MLFMA are used to accelerate the calculation of low-frequency and high-frequency regions, respectively. In this paper, the ill-conditioned matrix equations generated by discrete multiscale targets are accelerated by using the iterative method of multi-resolution ILU (MR-ILU) preconditioning. The validity of the dissertation method is proved by analyzing the actual multi-scale target electromagnetic properties.
