基于严格的电磁场理论 ,给出了一种新的分析平面传输线传输特性的空域及谱域的稳定变分公式 .该公式仅以槽口切向电场为未知参量 ,适用于各种开放和屏蔽的平面和共面传输线传播常数的计算 .该方法推导简单、计算速度快 .

A novel stationary variational formula in spatial domain and in spectral domain respectively for calculation of planar line propagation constant is presented based on the exact theory of electromagnetic field. The formula only involves the electric field in the slot, which is applicable to closed as well as open planar and coplanar line structure. The calculation is simple and fast. The result of slot line agrees well with that of spectral domain method.
