In this article, we propose a nonintrusive pulsed radiated susceptibility testing approach based on the long-line crosstalk setup. The objective is to reproduce the pulsed electromagnetic field coupling effect for wiring harness systems. The proposed test setup explores the crosstalk between parallel wires and imposes an additional pulse-driven wire to couple the interferences onto the wire under test. The transmission line model is exploited to represent both crosstalk and the pulsed field coupling process, demonstrating that equivalence can be achieved within a limited clearance time in general, provided the driven wire exceeds a critical length. In addition, rigorous equivalence can be obtained for particular incidences, such as broad-side illumination and end-fire excitation, under the condition of matched auxiliary equivalent terminals. Comparing this to state-of-the-art pulse injection approaches, the crosstalk-based testing method ensures the exact reproduction of field coupling effects without necessitating driven pulse predistortion, this characteristic underscores its robustness for pre-compliance pulsed field radiated susceptibility testing. Additionally, by considering a canonical double exponential interference, a pilot experiment is conducted to verify the equivalent rationale and feasibility of the proposed approach.

用于等效再现脉冲电磁场​​耦合线束效应的长线串扰注入方法


在本文中，我们提出了一种基于长线串扰设置的非侵入式脉冲辐射敏感性测试方法。目的是重现线束系统的脉冲电磁场​​耦合效应。所提出的测试设置探索了并行导线之间的串扰，并施加了额外的脉冲驱动导线以将干扰耦合到被测导线上。利用传输线模型来表示串扰和脉冲场耦合过程，证明只要驱动线超过临界长度，一般可以在有限的间隙时间内实现等效。此外，在辅助等效端子匹配的情况下，对于特定入射情况，例如宽边照明和端射激发，可以获得严格的等效性。与最先进的脉冲注入方法相比，基于串扰的测试方法可确保场耦合效应的精确再现，而无需驱动脉冲预失真，这一特性强调了其对预一致性脉冲场辐射敏感性测试的鲁棒性。此外，通过考虑典型的双指数干扰，进行了试点实验以验证所提出方法的等效原理和可行性。
