Abstract: This paper reviews the concep t and development of the wireless power transmission (WPT) and ana2 lyzes the three types ofWPT, i. e. , electromagnetic induction, electromagnetic resonance and electromagnetic radi2 ation with details. The electromagnetic induction WPT has a short transmission distance and low efficiency which needs to be compensated. The electromagnetic resonanceWPT is an update of the electromagnetic inductionWPT. It can transmitmedium power in severalmeters area and has a rather good development potential. The electromag2 netic radiationWPT can transmit power to a long distance with high power. But it needs high2efficient rectification antenna and high2directional antenna, which are difficult to be made.
