1. A wireless power receiver comprising:
- an electromagnetic resonator that includes;
a plurality of inductive elements connected in series and forming a receiver coil; and
a network of passive components comprising a plurality of capacitors arranged to form a matching network, the network of passive components comprising a first capacitor in parallel with a first inductive element of the plurality of inductive elements,wherein the electromagnetic resonator passively resonates at both a first resonant frequency and a second resonant frequency higher than the first resonant frequency to wirelessly receive power to provide to a rectifier electrically connected to the network of passive components, andwherein a quality factor of the electromagnetic resonator at both the first and second resonant frequencies is higher than a quality factor for inductive wireless power transfer.
