Description

technical field [0001] The present invention relates to the technical field of wireless power transmission, and more specifically, to a wireless power transmission system based on metamaterials. Background technique [0002] In recent years, with the increasing use of electronic products such as mobile phones and electric vehicles, wireless charging technology has received more and more attention. Compared with the traditional wired charging method, wireless charging has unique advantages such as portability and safety. At the end of the 19th century, Tesla proposed the conjecture of wireless energy transmission. After more than a century, the research on wireless power transmission has never stopped. Until 2007, Marin et al. of the Massachusetts Institute of Technology proposed a magnetically coupled resonant wireless power transmission, which lit a 60-watt power grid at a distance of two meters. Light bulb. This makes the study of wireless power transfer regain widespre...
