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 本文主要依据多导体传输线理论、二端口网络理论和天线理论对多芯电缆的耦合泄漏和辐射发射进行了较为详细的分析讨论。
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 在分析双绞线耦合泄漏时提出了空间旋转的模型,该模型较全面地反应了双绞线在空间360扭绞的真实结构,大大地提高了计算的精确度。
