Summary:
In this paper, a high-efficiency wireless energy transmission via magnetic resonance is experimentally implemented in a resonator with the various sizes of transmitting and receiving coils and the receiving coil having two shapes of rectangular and circular types. The transmission efficiency is analyzed by varying the transmission distance. The resonance between the transmitting and receiving coils is achieved with lumped capacitors terminating the coils. The transmission efficiency of the resonator consisted of the circular transmitting coil with the diameter of 60 cm and rectangular receiving coil with the length of one side of 10 cm is about 80 % at the transmission distance of 20 cm.
