Batteryless Radio and Ambient-Powered Receivers - SPICSE – From Maxwell to Modern RF Energy Harvesting #1006580

Can useful information be extracted from an electromagnetic wave without any external power? This deceptively simple question, first answered by the crystal detector more than a century ago, now sits at the heart of passive RFID, ambient RF energy harvesting, and battery-free IoT sensors.

*Batteryless Radio and Ambient-Powered Receivers* traces the continuous engineering thread from Maxwell’s equations through Hertz, Branly, Bose, Pickard, Armstrong and Hollmann to the quantitative design of modern ambient-powered systems. Written as a graduate-level reference, the book combines rigorous historical analysis with practical receiver architectures, energy-flow methods, and the physical limits that still govern today’s batteryless devices.

Readers will find:
- A clear narrative linking nineteenth-century semiconductor detection to contemporary zero-bias Schottky and RF-harvesting circuits  
- Engineering tools for antenna aperture, impedance matching, detector efficiency and energy storage under microwatt budgets  
- A detailed examination of Hollmann’s pioneering free-powered transistor receivers and their relevance to simultaneous wireless information and power transfer (SWIPT)  
- Design principles that remain valid for passive tags, energy-autonomous sensors and low-power European IoT deployments  

Ideal for RF engineers, graduate students in electronics and telecommunications, and researchers working on energy-autonomous systems, this volume offers both a coherent historical foundation and a working reference for the next generation of batteryless receivers.
