摘要：
In this paper, the effects of a transmitter on a receiver in the near field are presented to investigate the feasibility of microwave-based wireless power transfer. Especially, the input impedance (reflection coefficient) and power transfer efficiency of the Rx antenna are examined. In addition, a power transfer efficiency formula is proposed to obtain accurate efficiencies in the near-field as well as in the far field.
