摘要
针对越来越严重的信号畸变和线间耦合问题,应用时域有限差分法(FiniteDifference Time Domain,FDTD)建立了不均匀多导体传输线的仿真模型,并通过MATLAB编程对不均匀多导体传输线两端的电压响应进行了仿真分析.在此基础上,理论说明了各端口瞬态响应的波形特点.结果表明了时域有限差分法用于分析多导体传输系统电磁兼容问题的正确性和有效性,为电磁干扰的预测提供了有价值的参考信息.
Aiming at the problem of sig finite-difference time-domain（FDTD） me mission lines（MTL）is presented. Firstly nal distortion and inter-wire coupling, the thod for nonuniform multiconductor trans , the simulation model for nonuniform MTLis discussed. Then, the voltage response MATLAB programming. The results show f f of transmission line is analyzed using that the FDTD method is correct and ef icient for the electromagnetic compatibility（EMC）, providing valuable reference or prediction of electromagnetic interference（EMI）.
