多芯互连电缆信息辐射仿真研究
|
摘要
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。本文首先对基本理论进行了介
绍，然后在此基础上建立了多导体传输线模型。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。在分析芯线的辐射发射时利用线间耦合所得的实际
电流分布沿线长进行积分，得到场点的发射场强。本文还对多芯电缆转移阻抗及
屏蔽效能的测试方法进行了研究。最后编制了相应的程序并对仿真结果进行了详
细的分析验证。
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. 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. While discussing radiation the total field intensity is integrated along the line basing on the real current which is gained through crosstalk between lines. The testing method of multi-core cable transfer impedance and shielding effectiveness are also investigated in this paper. At last the emulational results of worked out program are analyzed and validated in detail.
