Integrated circuit (IC) and printed circuit board (PCB) electromagnetic (EM) modeling methods are becoming essential during the development of automotive electronic control units. Academic and industrial efforts focus on radiated and conducted emissions caused by flaws in PCB design from EM compatibility (EMC)/electrostatic discharge (ESD) point of view, including improper placement, grounding, and shielding of ICs. In this article, the effectiveness of noise suppressing sheet material for the mitigation of radiated emission at global positioning system (GPS) and Global'naya Navigatsionnaya Sputnikovaya Sistema (GLONASS) bands according to U.S. automotive original equipment manufacturer (OEM) requirements is investigated. A few test scenarios that include the NSS material are explored to gauge its performance in near-, intermediate-, and far-field regions, using 3-D full-wave numerical simulations and EMC laboratory experiments.

噪声抑制片材对缓解汽车辐射排放的有效性

在汽车电子控制单元的开发过程中，集成电路（IC）和印刷电路板（PCB）电磁（EM）建模方法变得至关重要。从EM兼容性（EMC）/静电放电（ESD）的角度来看，学术和工业领域的工作都集中在PCB设计缺陷引起的辐射和传导辐射上，包括IC的不正确放置，接地和屏蔽。在本文中，根据美国汽车原始设备制造商（OEM）的要求，研究了噪声抑制片材在缓解全球定位系统（GPS）和Global'naya Navigatsionnaya Sputnikovaya Sistema（GLONASS）频段辐射辐射方面的有效性。探索了一些包含NSS材料的测试方案，以评估其在近，中，
