针对暴露于频域和时域外部电磁场的印刷电路板 (PCB) 迹线的终端响应开发了紧凑的分析解决方案。基于散射电压公式中的传输线理论的分析使用准 TEM 传播模型来跟踪空气/电介质介质中外部电场的精确分布作为激励项。从任意波入射和终端阻抗获得的通用解中，导出了几个更简单的近似值，揭示了主要行为并指示了最小化耦合的相关参数。给出了对不同结果进行比较的实际例子。
Compact analytical solutions are developed for the terminal responses of a printed circuit board (PCB) trace exposed to an external electromagnetic field in the frequency and time domain. The analysis based on transmission line theory in a scattered voltage formulation uses a quasi-TEM propagation model for the trace and the exact distribution of the external electric field within the air/dielectric medium for the excitation terms. From the general solutions obtained for arbitrary wave incidence and terminal impedances, several much simpler approximations are derived revealing the principal behavior and indicating the relevant parameters to minimize the coupling. Practical examples with a comparison of the different results are presented.
