Efficient artificial magnetic conductor shield for wireless power
Artificial magnetic conductors (AMC) offer a solution to increasing link efficiency in inductive power transfer (IPT) while reducing magnetic fields outside the air gap. A practical design for an artificial magnetic conductor, suitable for use as a shield for inductive power transfer, is presented. The AMC makes use of a ferrite substrate and lumped capacitor loading. A model of the plane wave behaviour of the structure is compared to simulation and the performance of the AMC compared to other shielding solutions, in an IPT scenario. The plane wave behaviour is found not to provide a good prediction of the AMC behaviour in the IPT scenario. The AMC shield is found to offer the greatest link efficiency, in the IPT scenario.
