Tesla considered wireless power in the 1890s, as he labored over his breakthrough “Tesla coil” transformer circuit that generated alternating current electricity, but he couldn’t prove that he could control a beam of electricity across long distances. “The sheer fact that he could imagine it...
Currently, there is not only a great need for power harvesting but also in many cases it is necessary to send information along with power over the same channel like in a RFID scenario. The goal of this paper is to illustrate that these objectives of simultaneous power transfer and informatio...
The power transfer problem in SD-WSN was studied in (Ejaz et al., 2016) with aiming at real-time recharging ofsensor nodes. In this work, theSDNcontroller is in charge of finding an optimal position for the energy transmitters. Also, it can determine the minimum number of energy transmitte...
This paper proposes a simplified method for designing four-coil resonant wireless power transfer (WPT) networks by sequential application of impedance reflection through mutual inductances. Experimental validation is presented, and accuracy and limitations of the method are described. The method appears us...

The rectifier component of an RF-to-DC converter is a nonlinear circuit element due to the relationship between the circuit’s RF input power and DC output power. The waveform has an impact on the conversion efficiency.1Signals with high PAPR result in higher harvested DC powe...
The promise of worldwide wireless power transfer began with the pioneering work of Nikola Tesla about 100 years ago. His principal approach is summarized. The viability of such a system must still be demonstrated and many questions remai... KL Vanvoorhies,JE Smith - Intersociety Energy Conversion...
Wireless power transfer (WPT) is much researched and discussed in the context of IoT, electric vehicles and mobile electronic devices.
A 3D WPT system using a cylindrical transmitting coil excited by a single power source is proposed to improve flexibility and efficiency. Specifically, the coil size is designed and the circuit model...
