Beschreibung
Zusammenfassung:	A resonant wireless power receiver that includes an electromagnetic resonator having one or more inductive elements that are arranged to form a receiver coil and a network of passive components arranged to form a matching network. A rectifier circuit converts ac power from the electromagnetic resonator to dc power. An available-power indicator measures the rectified power to assess the instantaneous power available to the receiver.
