In their previous work, the authors proposed a methodology for predicting and modeling electromagnetic emissions in case of shielded coaxial cable with respect to the ground dielectric properties. In that work, a shielded coaxial cable was treated as a travelling wave antenna and the decomposed contribution of each phenomenon was validated through extensive electric field measurements of the cable over various ground planes and heights. In the present paper, the authors attempt to verify the applicability of this methodology in more complex structures; exploring the case of SpaceWire (SpW) cable over a carbon-fiber-reinforced polymer ground. This setup is of major interest for space applications, as it becomes the standard harness and grounding design for the majority of space missions. SpW is a space-application focused cable with four shielded twisted pairs employing low-voltage differential sign signaling, a geometry requiring rather cumbersome calculations in order to analytically extract the radiated emissions. The authors showcase that this issue can be bypassed with the proposed methodology, while measurements verify the validity of this claim also for the case of complex structures

验证在 CFRP 地面上布线的 SpaceWire/LVDS 链路的辐射发射建模。

在他们之前的工作中，作者提出了一种方法，用于在屏蔽同轴电缆的情况下根据接地介电特性预测和建模电磁辐射。在这项工作中，屏蔽同轴电缆被视为行波天线，并且通过在各种接地平面和高度上对电缆进行广泛的电场测量来验证每种现象的分解贡献。在本文中，作者试图验证这种方法在更复杂结构中的适用性；探索 SpaceWire (SpW) 电缆在碳纤维增强聚合物地面上的情况。这种设置对太空应用非常重要，因为它成为大多数太空任务的标准线束和接地设计。SpW 是一种空间应用聚焦电缆，具有四对采用低压差分符号信号的屏蔽双绞线，这种几何结构需要相当繁琐的计算才能分析提取辐射发射。作者展示了这个问题可以通过所提出的方法绕过，而测量也验证了这一说法的有效性，也适用于复杂结构的情况
