This letter compares the macro block-characteristic basis function method (MB-CBFM) with the modified accurate subentire-domain (ASED) basis function method to solve the interconnected finite periodic arrays. In the MB-CBFM, a compressed matrix equation whose size is less than that of the conventional CBFM can be obtained using the idea of macro blocks and the array theory. In the modified ASED method, a few sets of ASED bases on the cells are constructed by solving the subarray problem excited by the several plane waves. Afterwards, a reduced matrix equation will be obtained. The size of the matrix is greater than that in the MB-CBFM for the large-scale arrays. Numerical results obtained from the modified ASED basis function method are more accurate than those of the MB-CBFM.

MB-CBFM与改进的ASED基函数法分析互连有限周期阵列的比较



这封信将宏块特征基函数方法(MB-CBFM)与改进的精确子全域(ASED)基函数方法进行了比较,以求解互连的有限周期阵列。 MB-CBFM利用宏块的思想和阵列理论,可以得到比传统CBFM更小的压缩矩阵方程。在改进的ASED方法中,通过解决由多个平面波激发的子阵列问题来构造几组基于单元的ASED基。然后,将得到简化的矩阵方程。对于大规模阵列,矩阵的大小大于 MB-CBFM 中的矩阵的大小。改进的 ASED 基函数方法获得的数值结果比 MB-CBFM 的结果更准确。
