| 摘 要： | 用修正后的传输线方程对垂直的导体间的串扰进行了频域模拟，通过反傅立叶变换得到时域信号。模拟表明，虽然垂直放置可使串扰幅度大幅度降低，但交叉线中仍有较强的干扰，串扰幅度与各端接入的负载有很大关系，对干扰的原因进行分析。为了证明结果的正确性，对平行导体间的串扰用时域有限差分法和本方法进行模拟，得到一致的结果。该文对实际应用有参考价值。 |

| Abstract: | The modified transmission lines (TLs) equation is used in the analysis of crosstalk between perpendicular TLs in frequency domain. Time domain voltage waveform is obtained via inverse Fourier transform. The simulation indicates that strong coupling still exist between TLs in the perpendicular crossing case, and the reasons that cause this coupling are studied, and the magnitude of crosstalk is discussed. Finite-difference time-domain (FDTD) method is introduced to validate the simulations. All the presented results are valuable in practical applications. |
| Keywords: | transmission line crosstalk terminal frequency domain time domain finite-difference time-domain |
