RF (radio frequency) power transfer

RF (radio frequency) power transfer is a method of transmitting energy wirelessly using radio waves. Devices equipped with antennas convert electrical power into radio waves, which then travel through the air to another device's antenna. The receiving device captures the radio waves and reconverts them back into electrical power to operate or charge electronic devices. This technology is commonly used in applications like wireless charging for smartphones, RFID systems, and certain medical devices, offering a convenient way to transfer energy without physical connections.
