摘要：

Fundamental EMI source mechanisms leading to common-mode radiation from printed circuit boards with attached cables are presented in this paper, Two primary EMI source mechanisms have been identified: one associated with a differential-mode voltage and another associated with a differential-mode current, both of which result in a common-mode current on an attached cable, These mechanisms can be used to relate printed circuit layout geometries to EMI sources, The two mechanisms are demonstrated through numerical and experimental results, and an example from a production printed-circuit design is presented.
