<p>A wireless power transmitting system includes a first device which includes a first NFC interface which includes a first coil and a second device which includes a second NFC interface which includes a second coil and receives power from the first NFC interface by wireless. Wireless power transmission efficiency (η) between the first coil and the second coil is 0.1 or greater in a section in which a distance (d) between the first coil and the second coil is smaller than double the maximum diameters (Rmax) of the first coil and the second coil.</p> |
