A STUDY ON THE WIRELESS POWER TRANSFER EFFICIENCY OF ELECTRICALLY SMALL, PERFECTLY CONDUCTING ELECTRIC AND MAGNETIC DIPOLES

By C. L. Moorey and W. Holderbaum

Full Article PDF (218 KB)

Abstract:
This paper presents a general theoretical analysis of the Wireless Power Transfer (WPT) efficiency that exists between electrically short, Perfect Electric Conductor (PEC) electric and magnetic dipoles, with particular relevance to near-field applications. The figure of merit for the dipoles is derived in closed-form, and used to study the WPT efficiency as the criteria of interest. The analysis reveals novel results regarding the WPT efficiency for both sets of dipoles, and describes how electrically short perfectly conducting dipoles can achieve efficient WPT over distances that are considerably greater than their size.
