在这封信中，我们定量分析了两个线圈在近场/远场混合区工作的机理。特别是，我们建议从静态和辐射的角度来分离耦合，而不是模糊的近场或远场。阻抗矩阵模型的结果表明，这两种机制的支配作用取决于天线的几何形状和天线的布置。我们演示了如何利用混合耦合机制来获得最大增益和拓宽信道带宽。
In this letter, we quantitatively analyze the mechanism of two coils working in the near-field/far-field hybrid zone. In particular, we propose to separate the coupling in terms of static and radiative, rather than the ambiguous near or far field. The results of our impedance matrix model show that the domination of the two mechanisms depends on both the antenna geometry and the antenna arrangement. We demonstrate how one may take advantage of the hybrid coupling mechanism to acquire maximized gain and to broaden the channel bandwidth.
