Summary:
Wireless Power Transfer (WPT) system in accordance with Qi standard is being installed in smart phone in recent years. But the transmission efficiency is greatly deteriorated due to nearby metallic objects. To solve this problem, magnetic sheet with high permeability is set between WPT coil and nearby metallic objects. In order to make thickness of these materials thinner, we propose amorphous magnetic sheet. Besides this amorphous magnetic sheet causes to increase the transmission efficiency.
