Wireless Power Transmission

Wireless Power Transmission (WPT) is the process of transmitting electrical energy from a power source to a device without physical connections, using electromagnetic fields or radio waves. This technology enables gadgets like smartphones or electric vehicles to be charged remotely, increasing convenience and potential design flexibility. WPT typically involves a transmitter that converts electrical energy into electromagnetic energy, which then travels through the air or space, and a receiver that captures this energy and converts it back into usable electricity. It relies on principles like resonance and inductive coupling to efficiently transfer power over short to moderate distances.
