Wireless power transmission-part I: A brief history

In this part of the paper, authors have discussed the historical background of the wireless power transmission since the inception of it to the current state-of-the-art. This initial part of the paper may be regarded as the introductory part of authors' experimental studies on wireless power transfer via near-field coupling of electrically-small transmitting and receiving loop antennas which have been recently carried out at the Antenna and Propagation Laboratory, SKFGI, Mankundu. The theoretical modeling of the transmitting and receiving loop antennas as the wireless power transfer module and the corresponding experimental studies have been discussed in the successive parts later on as the continuation of the same paper.
