在这项研究中，一个无条件稳定的时域有限差分算法的时域分析的有源多导体传输线。将该算法的结果与传统算法的结果进行了比较。虽然该算法的结果有一个很好的精度，所提出的算法的CPU时间是小于（约90%），传统的。提取了新算法和传统算法的放大矩阵，并研究了它们的数值稳定性。对于任意时间步长，该算法的谱半径均小于1，且算法是无条件稳定的。
In this study, an unconditionally stable finite difference time domain algorithm for time domain analysis of the active multiconductor transmission lines is presented. The results of the proposed algorithm are compared with the results of the conventional algorithm. While the results of the proposed algorithm have a very good accuracy, the CPU time of the proposed algorithm is less than (about 90%) that of the conventional one. The amplification matrixes of the proposed and conventional algorithms are extracted and numerical stability of them are investigated. The spectral radius of the presented algorithm is smaller than one for any temporal step sizes and the proposed algorithm is unconditionally stable.
