  author={Andrea Massa and Giacomo Oliveri and Federico Viani and Paolo Rocca},
  journal={Proceedings of the IEEE},
The concept of long-range wireless power transmission (WPT) has been formulated shortly after the invention of high power microwave amplifiers. The promise of WPT, energy transfer over large distances without the need to deploy a wired electrical network, led to the development of landmark successful experiments, and provided the incentive for further research to increase the performances, efficiency, and robustness of these technological solutions. In this framework, the key-role and…
