摘要：
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.
