The Huygens’ box (HB) method allows an arbitrary printed circuit board (PCB) in a simulation to be replaced with a set of current sources on a closed surface. A numerical study of the method is performed with different noise sources, represented by its HB, in combination with different obstacles. The chosen combinations mimic radiation features of real PCBs and product environments. This study shows that if the ground plane and substrate are included in the HB, the accuracy of the HB method generally is good. However, if the coupling between the PCB and the obstacle is strong, the method fails at a few resonance frequencies. In the search for the methods general limits, it is shown that the method cannot predict the maximum radiated emission of power plane resonances without including the vias in the HB.

障碍物附近不同来源的惠更斯盒法评估

惠更斯盒 (HB) 方法允许将模拟中的任意印刷电路板 (PCB) 替换为封闭表面上的一组电流源。该方法的数值研究是在不同的噪声源下进行的,由其 HB 表示,并结合不同的障碍物。所选组合模仿真实 PCB 和产品环境的辐射特征。本研究表明,如果地平面和基板都包含在 HB 中,则 HB 方法的精度一般是好的。但是,如果 PCB 和障碍物之间的耦合很强,则该方法会在少数共振频率下失败。在寻找方法的一般限制时,表明如果不包括 HB 中的过孔,该方法无法预测电源平面谐振的最大辐射发射。
