Abstract:Abstract-This paper presents a new printed-circuit-board (PCB) resonator structure suitable for mega-Hertz wireless power transfer (WPT) applications. Unlike previous PCB resonators that can form only parallel resonant structures, the new designs can easily be configurated as either parallel or series resonators. The novelty of the resonator structure involves the replacement of the PCB material with an airgap in the main magnetic flux path of the resonator structure and adoption of air-trenches between adjac… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
