基于FEM的传输线时域串扰分析与实验研究

his paper utilizes Finite Element Method (FEM) to study the distribution of two parallel transmission lines electromagnetic field, and the simulation of time domain crosstalk response with different load impedance. The crosstalk coupling voltage is analyzed through adding the trapezoidal wave with 18 ns level rising edge at the port of the generator line. The SPICE simulation and the experimental data are compared with this simulation. The results showed that: The FEM simulation are basically consistent with the experimental results, and the simulation accuracy is greater than SPICE simulation accuracy with the matched impedance. It is proved that the FEM is available in the analysis of the crosstalk of transmission lines with ns level rising edge.
