Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

A hybrid methodology for developing the wireless power transfer (WPT) system is proposed in this paper. The transmitting $( Tx)$ resonator of the designed WPT with dimensions 40-by-40 sq. mm uses the advantage of the planar coil-based approach. On the other hand, the receiving resonator $(Rx)$ is miniaturized through the defected ground structure-based technique that resulted in the two times size reduction (20-by-20 sq. mm). Furthermore, the optimization of Tx and Rx is performed for the development of the hybrid WPT system. Finally, realized WPT, operating at 300 MHz, demonstrated a power transfer efficiency of 66%.
