Kertas kerja ini menerangkan mekanisme penjanaan mod biasa pada papan litar bercetak dengan corak tanah yang sempit. Talian penghantaran mempunyai nilai tahap ketidakseimbangan. Pada titik sambungan dua talian penghantaran yang mempunyai darjah ketidakseimbangan yang berbeza, voltan mod biasa dijana berkadar dengan perbezaan, dan ia memacu arus mod biasa. Penulis mencadangkan kaedah untuk menilai pengedaran arus mod biasa dan mengesahkannya dengan pengukuran. Walaupun arus mod biasa yang dikira lebih besar daripada diukur satu dengan beberapa dB, kedua-duanya adalah berkadar dengan tahap ketidakseimbangan. Teknik pengurangan EMI, 'padanan tidak seimbang,' juga dicadangkan.

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.
