Over the past few years, various metamaterials have been designed and applied in antenna systems. In this paper, a new structure of magnetic metamaterials is proposed for megahertz wireless power transmission, which can be manually adjusted to work at a variable frequency ranging from 10∼30 Mhz. The S parameters, resonant frequency, effective permeability of metamaterials are computed for analysis. The different substrates and layouts of metamaterial slab are also numerically evaluated by full-wave simulation. The specific magnetic metamaterial slabs with 17.6 MHz are fabricated and experimentally verified by the network analyzer. Finally, these slabs are applied in a more practical two-coil coupling system to evaluate their performance enhancement.
