摘要
阻抗矩阵的快速填充方法和快速求解方法是计算电磁学的研究重点。本文提出了一种新型的阻抗矩阵快速填充算法。该方法在几何分块的基础上,使用HRWG函数作为基函数和测试函数离散积分方程,得到该分块矩阵的稀疏化分解,并在此基础上实现矩量法的快速填充。数值举例表明该算法具有较高的精度和效率,能够用于电磁散射问题快速求解。
The fast methods for impedance matrix filling and solving are the focus in the computational electromagnetics society. In the present paper, a blocked matrix filling algorithm is proposed. Based on domain decomposition, in this method the HRWG functions are used as bases functions and testing functionsto discritize the EFIE and to obtain the sparse matrix decompositions, and finally to realize the blocked matrix filling. One numerical example is provided, which shows the proposed method can obtain required accuracy and efficiency. The proposed method is qualified for the fast solving of the electromagnetic scattering problems.
