【摘要】：金属腔体内的场线耦合是电磁兼容领域的一个重要的问题,基于模式匹配及BLT方程理论,该文提出一种计算带孔阵腔体内场线耦合的方法。将外部激励源对腔体内传输线的耦合分解为孔腔耦合和场线耦合两个过程,腔体内任意点的场强由模式匹配理论及矩量法计算得到,腔体内的场线耦合由Agrawal模型构建BLT方程进行计算。与测试数据对比得出,模式匹配理论可以准确计算腔体内部电磁场。与CST数值仿真数据对比得到,该方法可以准确计算任意入射波激励下线缆终端负载上的电流响应且计算效率高,可用于腔体内场线耦合的研究。
[Abstract]:The field line coupling in a metal cavity is an important problem in the field of electromagnetic compatibility. Based on the pattern matching and BLT equation theory, a method for calculating the field line coupling in a cavity with a cavity is proposed. The coupling of the external excitation source to the cavity in the cavity is decomposed into two processes, the cavity cavity coupling and the field line coupling, and the field of the arbitrary point in the cavity. The field line coupling in the cavity is calculated by the Agrawal model, which is calculated by the model matching theory and the moment method. Compared with the test data, the model matching theory can accurately calculate the internal electromagnetic field of the cavity. Compared with the CST numerical simulation data, the method can accurately calculate the cable excited by any incident wave. The current response of terminal load is high and the computation efficiency is high. It can be used to study the field line coupling in the cavity.
