Wireless Power Transfer (WPT) serves to transfer power from a grid or storage unit to a device without the need for cable connections. This can be performed by induction, as well as by using radio or microwaves.

The technology is already seeing widespread use; for example, for charging of cell phones and toothbrushes. R&D of WPT, especially inductive and resonance coupling WPT, has been active over recent years. The increased need to decarbonize the transport sector in particular is resulting in growing interest in electric vehicles and their comfortable charging.

This second edition of Wireless Power Transfer Technologies: Theory and technologies covers the very latest in theory and technology for WPT, for inductive and resonance coupling as well as radiative WPT with radio waves. It describes the theory as well as the technology and applications. Updates to the new edition include output characteristics of multi-hop systems, technologies, new experimental data, developments on regulation and standardization, WPT for dynamic EV charging, and far-field WPT.

After revising inductive and resonance coupling theory, chapters cover multi-hop wireless power transmission, circuit theory, power transfer via radio waves, antennas and phased arrays, transmitter, inverter and rectifier technology, WPT for electric vehicles, long-distance WPT, as well as biological and medical aspects.

This revised, expanded and updated new edition is a valuable resource for researchers in industry and academia involved with power systems and vehicles.
