[EMC]Cavity Model for the Slot Radiation of an Enclosure Excited by Printed Circuit Board Traces

Abstract—Traces on a printed circuit board (PCB) couple to the t"Ci1"U  
cavity consisting of the PCB ground plane and a metallic enclosure -&sY*(:n_  
cover. We introduce this common-mode coupling of a PCB trace (
De{r|
  
to the cavity field by an analytical model that is verified with 3-D }dop]{RG  
simulations using HFSS. The cavity field causes radiated emission Y*$>d/E  
fromthe slots of the cavity. For an accurate calculation of the cavity z4:<?K  
field inside the enclosure and the radiated emission, we consider c\2rKqFD8  
the radiation loss by amultiport approach. Comparisons of the an- 5e$1KN`  
alytical results for the radiated field to measurements show good hiBsksZRnk  
agreement. Radiated emission can be calculated for arbitrary geo- oWL_Hh%-f`  
metric enclosure shapes as a functio .. ;<N:!$p

恩，楼主是否在做PCB的EMI研究，有机会交流下

这篇文章很新啊。 Hb=#`  
关于PCB的谐振模型不少文章有介绍的，这篇也是对于规则矩形结构吧，之前我也根据矩形模型公式写了个谐振模型代码，只关注的板内的阻抗计算，貌似精度还行，也是参考的一篇文献。 E=s,-  
这类问题做做还是很有意思的。

看看，也做相关的工作！

好东西，感谢楼主

不错的文章，我也研究过。

谢谢楼主的共享

谢谢楼主咯  参考下 frbd{o  

看看，谢谢啦
