Claim Text:
1. A communication device using wireless power, the communication device comprising: a controller configured to control mutual resonance between a target resonator and a source resonator; a demodulator configured to demodulate information transmitted from the source resonator based on an amount of energy received from the source resonator; and a modulator configured to modulate information, wherein the controller controls the target resonator so that the target resonator receives energy, transmitted from the source resonator, through mutual resonance for one or more symbol duration times, wherein a symbol duration time is a cycle in which the source resonator is charged and discharged to transmit information, wherein the controller adapts a period of the mutual resonance, and wherein the modulated information corresponding to the adapted period is transmitted to a communication device including the source resonator.
