Applications of Metamaterials in Far-field Microwave Wireless Power Transfer at 2.45 GHz

Abstract

Wireless power transfer (WPT) is a technology that enables the transmission of electrical energy from a power source to a receiver without wired electrical connections. This technology has gained significant attention recently due to its potential applications in various industries, including consumer electronics, healthcare, transportation, and aerospace. There are several WPT techniques, including inductive coupling, magnetic resonance, laser power, and far-field microwave technologies. Each method has advantages and limitations regarding efficiency, range, and power transfer capacity. The technology can potentially revolutionise how we charge electronic devices, mobile ground and aerial vehicles, power medical implants, and transport energy over long distances.
