| Outline of Final Research Achievements |
A approach was developed to calculate the scattering matrix of the antennas in the near-field wireless power transfer system in a complex environment by using the method of moments to design the system with the maximum power transfer efficiency, Loosy matching circuits were successfully designed to improve the impedance matching condition. A method was proposed to compensate the change of input impedance of the antennas to solve the problem of efficiency reduction due to the change of the relative distance and position between the transmitting and receiving antennas in the system. In the proposed system, a parasitic array with a impedance switch in each array element is electrically controlled.
