Simulation Analysis on Coupling of Field to the Tree Transmission Lines Networks in the Reverberation Chamber
摘要/Abstract
为研究复杂腔室电磁环境下场线耦合规律, 提出了高效电磁防护的新方法.以典型树形传输线网络为研究对象, 分析其在混响室电磁环境下的响应信号.结合蒙特卡洛统计理论, 改进外场激励下多导体BLT方程构造全向辐射电磁环境下的传输线网络仿真模型, 求解网络各终端时域、频域电流响应.研究单端口负载、单管道长度改变对各终端电流响应的影响.分析不同材料、不同离地高度情况下终端感应信号规律.结果表明:混响室电磁环境条件下, 传输线网络单个管道长度的改变使各终端频域谐振点发生变化, 但单个终端负载变化不会对除该点以外的其他终端响应产生显著影响;传输线网络的双指数脉冲时域感应电流信号呈震荡衰减曲线, 并随传输线材料电导率的增大和离地高度的减小而减小.
Taking the typical tree transmission line network as the research object,we have analyzed its response under the electromagnetic environment in the reverberation chamber.Using the Monte Carlo statistical theory to improve the multi-conductor BLT equation under the incident field,we have built the model that under the omnidirectional irradiation electromagnetic environment.The time domain and frequency domain current responses were worked out.The influence on the inductive current was studied when the load of single port or the length of single tube changed.And the coupling law with different condition was analyzed.The results show that the change of single tube of the transmission lines networks would change the frequency resonant points of each port.The change of single port's load would not have marked influence to the other ports except itself.The current response of the double exponential pulse would be a oscillation attenuation curve.With the increase of electrical conductivity of transmission lines and the decrease of the distance from the ground,the value of the response would decrease.
