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

This paper presents the development of the defected ground structure (DGS)-based wireless power transfer (WPT) system and its performance enhancement by incorporating the double negative metamaterial. Initially, the WPT system realization is achieved by coupling two identical DGS-based resonators operating at the medical band of 405 MHz. Afterward, the metamaterial possessing negative permittivity and permeability is designed. The obtained results demonstrate increased power transfer efficiency (PTE) up to 38.5% at the 50 mm distance with metamaterial placed in between resonators.
