Analyse on Field to Typical Cable Networks Coupling in Reverberation Chamber's Diffuse Field
摘要/Abstract
为研究复杂电磁环境对多导体传输线干扰特性,进一步分析场线耦合规律,通过对多列入射波在空间角上离散模拟腔室内复杂电磁环境.利用Agrawal场线耦合理论分析树形、环形等线缆网络各节点处的响应信号,并搭建实验系统进行实验验证.结果表明:利用多列波叠加的方法能较好地模拟混响室的电磁环境,可用于混响室场线耦合方面的研究.混响室条件下,线缆网络节点频域感应信号幅值随频率升高而降低,且在某些频点出现电流峰值.干扰信号为双指数脉冲时,线缆网络节点的时域响应信号呈现震荡衰减规律,衰减时间与网络结构有关.
To study of the interference that complex electromagnetic environment coupling to multi-conductor transmission lines,further analysis of the laws of field coupling to lines was done.Electromagnetic environment in the reverberation chamber was simulated by scattering the incident angle of multiple incident waves.The Agrawal coupling theory was used to analyse the response of tree and annular transmission lines' node.The experimental system was built to validate the simulation method.The result shows that,the “full-radiation” electromagnetic environment built by scattering the incident angle of multiple incident waves was similar to the field in reverberation chamber,and it could be used to analyse the field line coupling in reverbration chamber.The value of the frequency domain response of cable networks would get lower with the increase in frequence.And there would be some current peaks at some frequences.When the interfering signal was double exponential pulse,the time domain response of cable networks would be oscillation attenuation,and the decay time depended on the structure of cable networks.
