1. A transmitter, comprising:

  • circuitry configured to;

    transmit a given signal to a receiver in a detection mode of the transmitter, whereinthe given signal is transmitted to the receiver via a first waveguide and a second waveguide, andthe first waveguide is on a side of the transmitter and the second waveguide is on a side of the receiver;

    detect, in the detection mode, a contact between the first waveguide and the second waveguide based on a level of the given signal, received by the receiver, that is one of equal to a first threshold value or larger than the first threshold value;

    switch from the detection mode to a communication mode of the transmitter based on the detected contact; and

    transmit, in the communication mode, a modulated signal via the first waveguide and the second waveguide to the receiver.
