Preface
Research and development in wireless power transfer technologies have witnessed
fast-growing advancements in various fundamental and application fields due to the
availability of highly developed analytical methods, measurement techniques,
advanced numerical simulation tools, and an increase in practical business demands.
The recent advancements have also been accompanied by the appearance of various
interdisciplinary topics.
This book puts state-of-the-art research and development in wireless power transfer
technologies together. It consists of 13 chapters that focus on interesting topics of
wireless power links (first 10 chapters), and several system technology issues (last 3
chapters), in which analytical methodologies, computational simulation techniques,
measurement techniques and methods, and applicable examples are investigated.
This book concerns itself with recent and advanced research results and brief reviews
on wireless power transfer technologies covering the aforementioned topics. The
advanced techniques and research described here may also be applicable to other
contemporary research areas in wireless power transfer technologies. Thus, I hope the
readers will be inspired to start or further their own research and technologies and
expand potential applications. Although the book is a collected edition of specific
technological issues, I strongly believe that the readers can obtain ideas and
knowledge of the state-of-the-art technologies in wireless power transfer.
I would like to express my sincere gratitude to all the authors for their outstanding
contributions to this book.
