Yes. It's done every time you use an RFID device.Can you power a circuit with electromagnetic waves, as opposed to a physical connection like with a wire?
The end-to-end efficiency of most remote EM wave power systems is laughable when compared to wired power transfers.Yes. It's done every time you use an RFID device.
It's also done with many small appliances that use wireless charging via and two-piece transformer.
There are significant inefficiencies and so powering large circuits is generally impractical.
