| 摘 要： | 静电放电火花产生的电磁脉冲会对电子系统的正常工作造成严重的干扰，甚至造成系统的损伤。利用时域有限差分法建立了静电放电火花产生的电磁场的数值模型，模型中充分考虑了放电电极上的静电荷对电场的影响。把由此模型放电计算的电磁场值与由此解析方法得到的场值进行了比较，结果吻合良好。由此可以用此模型来研究静电放电火花产生的电磁场与电子系统的能量耦合问题。

| Abstract: | Electromagnetic pulse (EMP) generated by electrostatic discharge (ESD) spark can severely interfere in normal operation of the electronic systems and even damage them. In this paper, a numerical model of electromagnetic fields generated by ESD spark is presented using Finite-Difference Time-Domain (FDTD) method, in which the influence of electrostatic charge on the electrode over the electric field is taken into account. Electromagnetic fields calculated by this model are compared with those by the analytic method and they make a good agreement with each other. Therefore, this model can be used to study the energy coupling problems between electromagnetic fields generated by ESD spark and electronic systems. |
