摘　　要：运用镜像法简化了偶模激励双面槽线的分析模型,基于平面传输线传播常数满足的稳定的变分公式,给出了仅以槽口切向电场为变量的传播常数满足的变分公式。该公式计算速度快,计算结果与谱域法计算结果吻合较好。The analysis model of the bilateral slot line excited by its even mode is simplified by the image theory. Based on the stationary variational formula satisfied by the propagation constant of planar line, the variational formula of the bilateral slot line propagation constant which takes only the slot tangential electric field as variable is given. The calculation done by the formula is simple and fast,and the results agree well with these calculated by spectral domain analysis.
