摘要:
为求解外场照射下线缆终端耦合响应和分析终端耦合响应的影响因素,基于BLT矩阵方程建立了三导体传输线的场线耦合模型,并通过GTEM小室内的场线耦合试验验证了所建模型的有效性.利用所建立耦合模型进行场照射下线缆终端耦合影响因素分析,结果表明:线缆在电短状态时,终端耦合电压随着线缆长度的增加而增大;线缆在电长状态时,线缆长度变化并不影响线缆终端耦合电压;线缆间距增大时,线缆终端耦合电压明显增加;外场入射角度增加时,线缆终端耦合电压单调减小;线缆终端耦合电压随外场极化角度的增加而单调增加;终端负载阻抗大小对高频耦合影响较大,对低频耦合影响较小.
Abstract:
In order to solve the terminal coupling response of the cable in the radiation field and analyze the influencing factors of the terminal coupling response, the field-to-cable coupling model of the three-conductor cable exposed in the field is built based on the BLT equation. The validity of the model is verified by the field-to-cable coupling test in gigahertz transverse electromagnetic(GTEM)cell. The influencing factors of the cable terminal response are analyzed with the model. The results show that the terminal coupling voltage increases with the increase of the cable length when the cable is electrically short. The length of cable does not affect the terminal coupling voltage when the cable is electrically long. The terminal coupling voltage increases with the increase of the distance between cables. The terminal coupling voltage monotonically reduces with the increase of the incident angle, and it monotonically increases with the increase of the polarization angle. The impedance of the terminal load has significant effect on the terminal coupling voltage at high frequencies, but has less effect at low frequencies.
