Preface

*Wireless Power Transfer – Recent Development, Applications and New Perspectives* reviews wireless power transfer (WPT) techniques with an emphasis on fundamentals, technical challenges, metamaterials, and typical applications. It describes WPT technology using magnetic resonant coupling and electric resonant coupling and presents the latest approaches to its practical implementation, operation, and

Power transfer depends on coil coupling, which depends on the distance between coils, alignment, coil dimensions, coil materials, number of turns, magnetic shielding, impedance matching, frequency, and duty cycle. Receiver and transmitter coils

The book discusses the difference between electromagnetic induction and magnetic resonant coupling, the characteristics of various types of resonant circuit topologies, and the unique features of magnetic resonant coupling methods. It summarizes the key technical issues of WPT systems in terms of efficiency, power, distance, misalignment, directional charging, and energy security. The book also offers a survey on the studies of metamaterial-based WPT systems. It presents the very latest in theory and technology of both coupling and radiative wireless power transfer. Lastly, the book presents some typical applications of WPT technology,

By reviewing the development and the current state of WPT methods over the last several years, this book offers readers a wide view of WPT techniques based on the inductive coupling effect of the non-radiative electromagnetic field. This emerging energy transmission mechanism has significant impacts on the pervasive applica-

Designed to be self-contained, this richly illustrated book is a valuable resource for a broad readership, from researchers to engineers and anyone interested in cutting-
