The Korea Electronics Technology Institute (KETI) announced that it succeeded in developing a magnetic-resonance-type wireless power transmission technology. According to this technology, the transmitter creates a magnetic field and radiates it to the receiver. The energy (electrical power) is delivered through this radiated magnetic field.
