| 摘 要： | 文章采用了基于Neville算法的自适应频率插值（AFS）技术,减少了计算滤波器S参数特性的时间。Neville算法是一个迭代的算法,在迭代的过程中得出插值多项式,因此不需要矩阵求逆,防止了矩阵病态产生的误差,增强了数值的稳定性。分析结果显示,AFS不仅节省了计算时间,也有较高的插值精度。

| Abstract: | In this paper,the adaptive frequency sampling（AFS） technique with Neville algorithm is proposed to reduce the total simulation time of calculating the filter scattering performance.Neville algorithm is a recursive tabular method and need no matrix inversion,so it can obtain a rational interpolation function without singularity problems.Numerical results show that AFS has good performances on both time saving and accuracy. |
