本文对计算共面波导（CPW）和微带线（MSL）等平面波导宽带电特性不确定性的不同方法进行了相互比较。事实证明，不确定性线性传播 (LPU) 方法可以提供与更一般的蒙特卡罗程序相当的结果。还研究了高阶项对不确定性传播的影响，发现可以忽略不计。
In this paper different approaches to calculate uncertainties in the wideband electrical properties of planar waveguides such as coplanar waveguides (CPW) and microstrip lines (MSL) are compared against each other. The linear propagation of uncertainties (LPU) approach is demonstrated to give comparable results to the more general Monte Carlo procedure. The influence of higher order terms in the propagation of uncertainties is also investigated and found to be negligible.
