1. A wireless power transceiver, comprising:
- a power receiver comprising a receiving resonator that receives an inbound power from a source resonator;
a power transmitter comprising a transmitting resonator that transmits an outbound power to a target resonator;
a coupling controller configured to control a coupling frequency between the target resonator and the transmitting resonator; and
an isolator configured to electrically isolate the power receiver and the power transmitter to reduce interference between the receiving resonator and the transmitting resonator.

29. A wireless power transceiver comprising:
-
a power receiver comprising a receiving resonator that receives an inbound power from a source resonator; a power transmitter comprising a transmitting resonator that transmits an outbound power to a target resonator; and a coupling controller to control a coupling frequency between the target resonator and the transmitting resonator, wherein the coupling controller is configured to control a frequency such that a reflected wave of a transmission signal transmitted from the transmitting resonator to the target resonator has a minimum amplitude, and to set the controlled frequency as the coupling frequency.
