Calculation of Inductance of Directional Couplers with GNES Approach ──Generalization of Geometrization-Number Theory-Eliminating Singularity Approach in the Theory of Electromagnetism

应用GNES方法计算微波定向耦合器的电感．证明TEM波模式下柱导体是等矢势体，给出了矢势和面电流的基本奇性积分方程组．具体计算了各种组态下双圆杆内导体的电感，并得到了零级近似的解析表达式．

In this paper, the GNES approach is applied to calculate the inductance of directional couplers. It is proved that the inner conductors is equal-potential (vector potential)body in the TEM microwave modes. A basic singular integral equation system is formulated.The inductance per unit length of the directional coupler with double cylinder inner conductors are calculated in a variety of configurations. An analytic expression of these inductances in zero order approximation is also provided.
