In this letter, a mode reconfigurable resonator insensitive to its alignment is proposed. The resonator is capable of maintaining a wireless power transmission (WPT) efficiency without degradation of its performance caused by misalignments. After optimum mode selection, the average WPT efficiency of 66.71% (59.02 to 71.34%) in the azimuthal plane is measured at the transmitting distance of 20 cm. The result shows that the resonator can maintain a WPT efficiency with less than 12.5% of variation. Therefore, it is expected that the resonator would be a good solution for the practical applications demanding alignment-free in mid-range and high efficiency WPT systems.
