Abstract
In this paper, a compact triplex-layer and low-frequency metamaterial design scheme is presented. The triplex-layer metal cell can be extended easily and allows for the construction of 5x5 unit-cell sample with dimensions of 36mm x 36mm and operating at a working frequency of 6.78MHz. Results show that using the metamaterial sample in a wireless power transfer (WPT) system results in an efficiency enhancement of 26.8% at a working distance of 15 cm. From simulations and experiments, it is found that the proposed system outperforms two-layer metamaterial-coupled WPT system in terms of efficiency, range and size.
本文提出了一种紧凑的三层低频超材料设计方案。三层金属电池可以很容易地扩展，并允许构建5x5单元电池样品，尺寸为36mm x 36mm，工作频率为6.78MHz。结果表明，在工作距离为15 cm的无线电力传输系统中使用该超材料样品，效率提高26.8%。仿真和实验结果表明，该系统在效率、范围和尺寸上都优于两层超材料耦合WPT系统。
