Wireless power and communication systems using magnetic vector potential

摘要

Apparatuses and methods are provided for driving an input conductor with a signal comprising a series of voltage pulses. The pulses can beneficially invoke the skin effect to generate a time-varying magnetic vector potential that projects radially from a surface of the input conductor. The time-varying magnetic vector potential can provide an electric field for inducing output voltage pulses in an output circuit. The input conductor and output circuit can have various configurations. For example, the input conductor can extend along a plane, and the output circuit can at least partially reside in the plane and extend away from the input conductor in the plane. Such a geometry can reduce any back coupling between the two circuits, e.g., between electromagnetic fields caused by any current in the two circuits. Such a geometry would not normally allow for induction between the two circuits, which can reduce any Lenz effects.
