Wireless Power: From Ambient Harvesting to the 6G-Powered City is a clear, practical training guide to one of the most exciting fields in modern engineering: powering devices without traditional wires.
Written in a teaching style that connects beginner-friendly explanations with real engineering science, this book takes readers from the foundations of electromagnetic waves to antennas, RF energy harvesting, rectennas, supercapacitors, power management circuits, battery-free IoT, safety standards, 6G power delivery, and space solar power.
The book avoids unrealistic "free energy" claims. Instead, it teaches readers how to think like engineers: identify the energy source, calculate power density, understand path loss, measure efficiency, store harvested energy, and match the power system to the real load.
Inside, readers will find:
- Clear explanations of wireless power transfer and ambient energy harvesting
- Tables, diagrams, equations, glossary terms, and worked examples
- Practical lessons on antennas, rectifiers, impedance matching, PMICs, and storage
- Safety-focused discussion of RF exposure, medical implants, and regulation
- Future-looking chapters on 6G power spots and space solar power
- A master reference section and index for technical study
This book is designed for students, inventors, makers, engineers, researchers, and curious readers who want to understand what wireless power can do today, what it cannot do yet, and how future systems may reshape cities, sensors, and energy infrastructure.
Wireless power is not magic. It is energy, physics, design, measurement, and discipline.
