| Abstract: | Abstract: This paper reviews the concep t and development of the wireless power transmission (WPT) and ana2lyzes the three types ofWPT, i. e. , electromagnetic induction, electromagnetic resonance and electromagnetic radi2ation with details. The electromagnetic induction WPT has a short transmission distance and low efficiency whichneeds 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 electromag2netic radiationWPT can transmit power to a long distance with high power. But it needs high2efficient rectificationantenna and high2directional antenna, which are difficult to be made. |
