in this paper, the crosstalk and radiation of multiple-core cable is analyzed according as the multiconductor transmission line, two ports network and antenna theory . firstly the fundamental theories are presented 本文主要依據(jù)多導體傳輸線理論、二端口網(wǎng)絡理論和天線理論對多芯電纜的耦合泄漏和輻射發(fā)射進行了較為詳細的分析討論。
then multiconductor transmission line model is established . a spinning model is brought forward while analyzing the crosstalk of twisted-pair . it roundly shows the actual structure of twistedpair and greatly improves the calculating precision 在分析雙絞線耦合泄漏時提出了空間旋轉的模型,該模型較全面地反應了雙絞線在空間360扭絞的真實結構,大大地提高了計算的精確度。
