| 摘 要： | 野外有线通信受干扰时,被复线因耦合空间电磁能量而产生的干扰常常是被忽视的因素。基于Agrawl场线耦合传输线理论,利用时域有限差分技术建立了双线传输线电磁场耦合计算模型,对传输线对空间电磁波的时域耦合响应进行了仿真计算,总结了场线耦合的一般性规律,分析了对差分信号接收电路产生干扰的机理,验证了被复线的空间电磁能量耦合是野外有线通信受扰分析不可忽视的因素,提出了利用被复线进行有线通信时减少空间电磁耦合的建议。 |

| Abstract: | Based on Agrawl field-to-wire coupling theoretical transmission-line model,the relevant computer model of two-wire transmission line coupling to external electromagnetic filed is established by making use of Finite Difference Time Domain method.And then,the simulation of the wire-to-field coupling response is made.The principium of the response interference to difference signal receiving circuit is analyzed.Finally,the proposals is provided in order to reducing such interference in wire communication with coated wires. |
| Keywords: | coated wires transmission-line model finite difference time domain induced voltage |
