This book covers the next generation of power transfer in which power is transmitted via energy harvesting applications. It describes far-field wireless power transfers (WPT) and why it is considered a special type of power transfer where power is transmitted through wireless power sources like radio waves, Wi-Fi, and TV broadcasting signals rather than utilizing near field wireless power sources. The book is the first of its kind to explain far-field WPT and energy harvesting technology from the same viewpoint. It provides you with an application-oriented review of how the latest WPT and energy harvesting tech can solve practical real-world problems. You get insight to R & D activities and regulations for commercial products in the future market. The book helps you understand the theory of far field WPT, and you will learn about the rising market for power transfer, factory automation (FA) and Internet-of-Things (IoT) sensors. With its comprehensive and unique coverage combining WPT and energy harvesting technology, this is an excellent resource for researchers, graduate students and engineers looking to further their knowledge on the theory of far field wireless power transfer.
