A magnetic vector potential based communications system

摘要

A communication system using a magnetic vector potential as a signal propagation medium includes a sending device (11, 21) for generating a magnetic vector potential by passing an alternating current through a coil winding and a receiving device (12, 22) for measuring an electric field generated by a time variation of the magnetic vector potential. On the sending device side, a high frequency current modulated in accordance with a signal to be sent is passed through a coil winding wound around a toroidal core made of a magnetic substance to generate a magnetic vector potential. On the receiving devices side, an electric field generated by propagation of the magnetic vector potential is sensed by an electric field sensor. The sensed electric field is a received signal. <IMAGE>
