Experiments on adjustable magnetic metamaterials applied in megahertz wireless power transmission
Source abstract
Abstract
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.
