Experiments on adjustable magnetic metamaterials applied in megahertz wireless power transmission

Experiments on adjustable magnetic metamaterials applied in megahertz wireless power transmission

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 1...
