摘要
运用电磁理论和传输线理论,将场和路的分析方法结合起来,建立矩形巷道的等效传输线模型,简化了计算过程,为电路仿真奠定了基础.作为计算实例,对电场水平极化(1,1)模的RLCG分布参数进行计算,获得的结论具有一般性,分析方法可用于其它模式电磁波.通过衰减率的计算,得到与模式匹配理论分析相一致的结果,验证了等效传输线法的有效性.
Based on the equivalent transmission line method, which combined electromagnetic field and circuit theory, the transmission line model in a rectangular tunnel was given. The method predigested the calculating process, and established the foundation of the circuit emulation. As examples, the RLCG coefficients of the equivalent circuit for the dominant mode of the horizontal polarization electromagnetic wave in the rectangular tunnel were computed. The coefficients of other wave mode were also analyzed by this method. Consistent result with the pattern matching theoretical one was obtained for the attenuation rate, and the validity of the presented method was thus verified.
