Abstract

This paper explores the impact of geometric parameter uncertainties on transmission line crosstalk, crucial to electromagnetic compatibility for modern electronic systems. It reviews existing EMC research and methods for quantifying uncertainty, focusing on a two-conductor transmission line affected by uncertainties in height (h), conductor radius (rw), and spacing (d). Sensitivity analysis employs the Monte Carlo Method, Unscented Transform Method, and Stochastic Collocation Method, coupled with Finite Difference Time Domain simulations. Results show that the Unscented Transform Method is more suitable for this problem due to nonlinearity. In general, the radius (rw) has less impact, and the height (h) has more impact than the spacing (d), but for fast transitions, d has more impact than h. Additionally, a similarity exists between the standard deviation of crosstalk (NEXT and FEXT) and the time derivatives of the crosstalk means and the source signal. These findings highlight the implications for signal integrity in high-speed systems.

输电线路串扰对几何不确定性的敏感性分析

本文探讨了几何参数不确定性对传输线串扰的影响，这对现代电子系统的电磁兼容性至关重要。它回顾了现有的电磁兼容研究和量化不确定性的方法，重点是受高度 (h)、导体半径 (rw) 和间距 (d) 不确定性影响的双导体传输线。灵敏度分析采用蒙特卡罗法、无痕变换法和随机定位法，并结合有限差分时域模拟。结果表明，由于非线性，无痕变换法更适合这一问题。一般来说，半径（rw）的影响比间距（d）小，高度（h）的影响比间距（d）大，但对于快速转换，d 的影响比 h 大。这些发现强调了高速系统中信号完整性的影响。
