In this article, we rederive the formulas and discuss constraint rules for the S-parameters’ retrieval and the wideband extraction of per unit length resistance, inductance, conductance, and capacitance, and propagation constants of multiconductor transmission lines. To effectively solve the mode aliasing problem and improve the efficiency and the robustness in extracting above characteristic parameters of the quasitransverse electromagnetic mode multiconductor transmission lines, a wideband improved mode tracking algorithm based on the Hermitian inner product is proposed. Simulation experiments are designed and the extracted results by the proposed algorithm are compared with those from various commercial software (HFSS, Cadence Sigrity PowerSI, and Polar Si9000). The excellent data consistency, the better high-frequency data continuity, as well as the wider frequency intervals powerfully prove that the proposed extraction algorithm has the superb high-frequency stability and smaller computation amount, while extracting the wideband parameters correctly.

采用改进模式跟踪算法的多导体传输线宽带 RLGC 提取新方法


在本文中，我们重新推导了公式并讨论了 S 参数的检索以及单位长度电阻、电感、电导和电容以及多导体传输线的传播常数的宽带提取的约束规则。为了有效解决模式混叠问题，提高准横电磁模式多导体传输线上述特征参数提取的效率和鲁棒性，提出一种基于厄米特内积的宽带改进模式跟踪算法。设计了仿真实验，并将所提算法提取的结果与各种商业软件（HFSS、Cadence Sigrity PowerSI 和 Polar Si9000）的提取结果进行了比较。优异的数据一致性、更好的高频数据连续性以及更宽的频率间隔有力地证明了所提出的提取算法在正确提取宽带参数的同时具有极好的高频稳定性和较小的计算量。
