Modeling and comparison of different edge radiation suppression methods in printed circuit boards

This paper investigates and compares eight most frequently used edge radiation suppression methods. Optimization and improvement for each method are discussed to achieve better radiation suppression performance. In addition, many helpful design guidelines are obtained through a comprehensive comparison of these methods, to guide better EMC design for PCB. Base on this work, one can get a good guideline for the selection of edge radiation suppression method.
