Wireless Power Transfer (WPT) is considered to be an innovative game changing technology. The same radio wave and electromagnetic field theory and technology for wireless communication and remote sensing is applied for WPT. In conventional wireless communication systems, information is "carried" on a radio wave and is then transmitted over a distance. In WPT however, the energy of the radio wave itself is transmitted over a distance. Wireless communication technology has proven to be extremely useful, however in future it should be even more useful to apply both wireless communication and wireless power technologies together.

There are various WPT technologies, e.g. inductive near field WPT, resonance coupling WPT, WPT via radio waves, and laser power transfer. Recent Wireless Power Transfer Technologies via Radio Waves focusses on recent technologies and applications of the WPT via radio waves in far field. The book also covers the history, and future, of WPT via radio waves, as well as safety, EMC and coexistence of radio waves for WPT.

Technical topics discussed in the book include:

• Radio Wave Generation
• Radio Wave Amplification with Solid States Circuit and Microwave Tubes
• Antenna and Beam Forming Technologies
• Radio Wave Conversion/Rectification to Electricity
• Battery-less Sensor Applications toward Internet of Things (IoT)
• Solar Power Satellite Application
• Safety, EMC, Coexistence of Radio Waves for the WPT
