Power Transmission Determined by the Mutual Impedance and the Transducer Power Gain in the Near Field Region

This paper describes the role of mutual impedance and the transducer power gain which comes from key parameters to determine the amount of wireless power especially in a near-field environment. These two key parameters are applied to the two configurations; one is a dipole-dipole, and the other is a dipole-metal plate-loop configuration. Discussions are given on the achievable maximum power transfer between the sender and the receiver affected by the matching and the pass blockage.
Key words: Wireless Power Transfer, Mutual Impedance, Transducer Power Gain, Matching
