Can useful information be extracted from an electromagnetic wave without any external electrical power?
That deceptively simple question was answered more than a century ago by the crystal detector. The same physical principle-passive rectification of radio-frequency energy-underpins today's passive RFID tags, ambient RF energy harvesters, and battery-free sensor nodes. Between those two eras lies a continuous engineering thread that has rarely been examined as a single narrative.
*Batteryless Radio and Ambient-Powered Receivers* traces that thread from Maxwell's equations through Hertz, Branly, Bose, Pickard, Armstrong, and Hollmann, then develops the quantitative tools needed to design modern ambient-powered receivers. Historical material is clearly distinguished from engineering interpretation; original analysis and novel receiver architectures are identified as such.
The book provides:
- A rigorous historical foundation of semiconductor radio detection
- Complete engineering treatment of RF energy harvesting, impedance matching, zero-bias Schottky detectors, multi-stage rectifiers, and energy storage
- Systematic re-examination of the classical crystal receiver using modern energy-flow analysis (Receiver Energy Cascade Analysis)
- A family of five original ambient-powered receiver architectures (Basu Mk-I through Mk-V), ranging from enhanced crystal sets to regenerative and dual-path SWIPT designs
- Numerical simulation methods and practical design guidelines
Intended for graduate students, RF engineers, and experienced radio amateurs, this volume serves both as a scholarly reference and a working design handbook. Equations, sidebars, engineering lessons, and performance metrics equip the reader to move from historical insight to practical, battery-free systems.
From the spark-gap experiments of the 1880s to the nanopower electronics of the 2020s, the fundamental challenge remains the same: harvest every available microwatt and convert it into useful information. This book shows how.
