This paper presents a geometric approach for the enhancement of the coupling coefficient between two magnetically coupled coils. It is demonstrated that the coupling coefficient can be considerably enhanced, if the turns of the coils are not concentrated at the circumferences, but distributed across the diameters. For analysis, each of the two coils is assumed to be composed of concentric circular loops. The experimental results are in very good agreement with the theoretical results.
本文提出了一种用于提高两个磁耦合线圈之间耦合系数的几何方法。结果表明，如果线圈的匝数不是集中在圆周上，而是分布在直径上，则耦合系数可以显著提高。为了进行分析，假设两个线圈中的每一个都由同心圆环组成。实验结果与理论结果非常吻合。
