| 摘 要： | 针对串扰这一高频电子电路多发现象,从时域有限差分法这一有效的电磁学计算工具出发,给出了π型Leapfrog中心差分格式的理论推导. 利用时域有限差分法计算出三芯线在集总参数模型、分布参数模型以及外施场激励条件下的“场-线耦合”模型三者的串扰值理论值,并与三维电磁场软件CST Studio Suite的仿真结果进行对比,验证了此方法的准确性与可靠性.

| Abstract: | Aiming at the high frequency electronic circuit of the crosstalk multiple phenomenon,from the point view of the finite difference time domain(FDTD)method as an effective tool of electromagnetism calculation,this article gives a theoretical derivation of π type Leapfrog central difference scheme. It uses the finite difference time domain method to calculate the theoretical value of the lumped parameter model,distribution parameter model,and field-line coupling model under external excitation condition comparing with the simulation results of the 3d electromagnetic field software CST Studio Suite. The accuracy and reliability of this method are verified. |
