Cooperative wireless power transmission method based on time reversal technology

In the wireless power transfer systems using microwave, power conversion efficiency (PCE) represents a major challenge, especially at low input power levels. In this paper, a cooperative wireless power transmission method based on time reversal technology is developed to achieve a high input voltage. The performance of the proposed approach is investigated by using numerical experiments. Experimental results indicate that the input voltage can increase by more than 5.5 times over that of the general wireless power transmission.
