본 논문에서는 좁은 접지 패턴을 갖는 인쇄 회로 기판의 공통 모드 생성 메커니즘에 대해 설명합니다. 전송선에는 불균형 정도의 값이 있습니다. 불균형 정도가 서로 다른 두 전송선의 연결점에서는 그 차이에 비례하여 공통 모드 전압이 발생하고, 이는 공통 모드 전류를 구동합니다. 저자는 공통 모드 전류 분포를 평가하고 측정을 통해 검증하는 방법을 제안합니다. 계산된 공통 모드 전류는 측정된 전류보다 몇 dB만큼 크지만 둘 다 불균형 정도에 비례합니다. EMI 감소 기법인 '불평형 매칭'도 제안된다.

Tetsushi WATANABE, Osami WADA, Takuya MIYASHITA, Ryuji KOGA, "Common-Mode-Current Generation Caused by Difference of Unbalance of Transmission Lines on a Printed Circuit Board with Narrow Ground Pattern" in IEICE TRANSACTIONS on Communications,
vol. E83-B, no. 3, pp. 593-599, March 2000, doi: .
Abstract: This paper explains a mechanism of common-mode generation on a printed circuit board with a narrow ground pattern. A transmission line has its value of degree of unbalance. At a connection point of two transmission lines having different degrees of unbalance, common mode voltage is generated proportional to the difference, and it drives common mode current. The authors propose a method to evaluate common mode current distribution and verify it by measurement. Although calculated common mode current is larger than measured one by a few dBs, both of them are proportional to the degree of unbalance. An EMI reduction technique, 'unbalance matching,' is also proposed.
