Compact Triplex-layer Metamaterials Design for Wireless Power Transfer Efficiency Enhancement

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...
