Abstract

Measurement and modeling of the undesired electromagnetic waves (electromagnetic noise) from electronic devices play an important role in the understanding of EMI problems and in establishing design techniques. One of the methods of analysis of the EMI problems of electronic devices is the measurement of the common mode current flowing in the cables connected to the electronic devices. This paper reviews the measurement of the common mode current on printed circuit boards (PCB) and discusses results related to the EMI problems of PCB. FDTD modeling of the common mode current by traces placed near the PCB edge and suppression of the common mode current by the guard band are described.
