about

Nikola Tesla's dream in the early 20th century of a "World Wireless System" led him to build the Wardenclyffe Tower, a prototype base station serving as an emitter for his "World Wireless System." The base station was to supply wireless electrical energy to a distant receiver. This book builds upon that dream and is a result of intensive research in powerline, machine to machine communications, and wireless power transfer globally.

Wireless energy transfer or Witricity (WIreless elecTRICITY) transfers electricity instead of data. The technology is useful in cases where instantaneous or continuous energy is needed but interconnecting wires are inconvenient, hazardous, or impossible. The transfer is made through inductive coupling and electromagnetic radiation. Inductive coupling provides optimum power delivery to a receiver load if both the emitter and the receiver achieve magnetic resonance concurrently. Energy transfer systems mostly use antennas operating in their near field regions. As fossil energy sources are being depleted rapidly worldwide and oil prices soar, solar energy enhanced with wireless power transfer (WPT) has become a reasonable alternative for renewable energy and power harvesting. They are finding use in transportation, electric and hybrid vehicles, very fast trains, and the emerging field of Internet of Things.

Leading experts on the subject wrote this book on wireless energy transfer technology and its applications. The publication introduces and explains the technology in great detail and provides the theory and practice of WPT through the two approaches of coupled mode theory and circuit theory. Both approaches are dependent on resonance techniques. The level of presentation is suitable for design and training. In-depth coverage is provided on near field concepts; coupled-mode theory and models; circuit models of inductive antennas; radiative and inductive wireless power transfer, wireless power relay concepts, optimization techniques for wireless power transfer systems, control of wireless power transfer systems, and wireless charging concepts; and wireless energy transfer applications in electric vehicles, embedded medical systems, and the propagation in human tissues.

Each chapter covers a selected aspect of wireless energy transfer. The authors have gone to great lengths to provide worked examples in order to assist the reader in working through some of the difficult concepts and allow more understanding. The book is an excellent foundation for applying wireless energy transfer technologies in most fields, including transportation, communication, home automation, biomedical systems, and home appliances. It is a recommended read for practitioners and engineers in the power industry, students in universities, and research institutes. Honors and post graduate students in Physics, electrical/electronic engineering, and computer science will find the text easy to read and apply because of the mode of presentation.
