Abstract (in Japanese) (See Japanese page) 
(in English) Wireless power transmission with magnetic resonance from the transmitter resonator on the ground to an electric-powered toy helicopter in air was challenged. Impedance matching is very important for effective power transmission to an object moving in 3-D space. The objective of this demonstration is to validate the theoretical relation between transmission distance and efficiency with impedance matching. Another objective is to develop an efficient, compact, and light-weight resonator as a receiver. The relationship between the efficiency and altitude was shown for the case with impedance matching on the transmitter side. The result indicates that this one-side impedance matching is enough for the helicopter to lift up from the ground.
