1. A data reception apparatus comprising:

  • an energy discharger configured to discharge, prior to the data reception apparatus receiving data from an energy receiving apparatus, energy stored in a source resonator during a mutual resonance between the source resonator and a target resonator; and

    a demodulator configured to demodulate data received from the energy receiving apparatus based on an amount of energy transmitted from the target resonator in response to the energy stored in the source resonator being discharged,wherein the source resonator receives energy from the target resonator based on a mutual resonance that is generated in response to the energy stored in the source resonator being discharged, andin response to a charge in the target resonator reaching a predetermined value, a switch is turned on to connect a capacitor to the target resonator and charge a resonant frequency of the target resonator, and in response to the charge in the target resonator being less than a predetermined value, the switch is turned off to make the resonant frequency of the target resonator identical to a resonant frequency of the source resonator.
