Abstract:
The present invention provides a wireless transponder comprising: a receiver unit that receives an electromagnetic input signal; an input converter unit that converts into an acoustic wave the electromagnetic input signal received by the receiver unit; a delay unit provided in a direction in which an acoustic wave generated by the input converter unit propagates; an output converter unit that converts into an electromagnetic output signal the acoustic wave which has propagated inside the delay unit; and a transmitter unit that transmits wirelessly the electromagnetic output signal generated by the output converter unit.
