1. An electromagnetic induction wireless communication system comprising a transmitter, the transmitter comprising:

  • a magnetic antenna comprising a single magnetic coil positioned at a first location adjacent to a living body, wherein the magnetic antenna is configured to generate a reactive magnetic field in a near-field region of the magnetic antenna, wherein the reactive magnetic field is passed through the living body, which further generates an electric field coupled to the living body, wherein the electric field has a direction perpendicular to a surface of the living body and is available around the living body; and

    a signal source configured to produce a communication signal used to drive the magnetic antenna to produce the reactive magnetic field, wherein the transmitter when positioned at the first location on the living body is configured to communicate with a receiver of the electromagnetic induction wireless communication system that is positioned at a second location on the living body using a combination of both the electric field and the magnetic field.
