Antennas receive and transmit electromagnetic waves, delivering information to our radios, televisions, cellphones and more.

The efficiency of wireless charging systems is limited by power loss occurring due to frequency changes in the resonant circuits that enable power transfer. These necessary modulations reduce ...
