Identifying dominant factor of EM radiation from asymmetrical differential-paired lines with equi-distance routing

Multi-channel differential-signalling scheme is one of the key technologies for modern electronics systems. For actual system, the ideal balance or symmetrical topology cannot be established, and hence, an imbalance component is excited. To provide the basic considerations for establishment of predicting the EM radiation from practical differential-paired lines, this paper attempts to quantify the correlation between imbalance components and EM radiation from asymmetrical differential-paired line with different equi-distance routing. Finally, the dominant radiation factor is identified using our proposed model.
