摘　　要：分块阻抗矩阵迭代算法(Block-IterativeAlgorithm)是一种非常直接而有效的求解多导体散射的加速求解算法。然而当单导体尺寸较大时,求解多导体散射的宽频带特性时仍然存在较费计算资源问题。基此,提出采用一种有效的Padé逼近型[Z]阻抗矩阵内插技术与分块阻抗矩阵迭代算法相结合的方法来快速分析多导体的宽频带电特性;计算结果与已有结果吻合较好,并且大大节省了计算资源,从而说明了该方法的快速性和精确性。Block-iterative algorithm is a very direct and effective method to speed up the scattering analysis of multi-objects. However, it still costs much computing resources when the single object became larger. A fast and effective wide-band analysis of multi-object scattering by impedance-matrix interpolation combined with block-iterative algorithm is presented in this paper. Some numerical results are given to illustrate the effectiveness and the accuracy of the proposed method.
