Abstract: Development and optimization of printed spiral coils have significant impacts on the power transfer efficiency (PTE) and operating range for magnetic resonant wireless power transfer (WPT) applications. In this paper, the effects of different material losses (substrate and conducting coating) of printed coils are considered and experimentally studied. For the purposes of comparison and finding the dominating losses, lossy loaded capacitors with equivalent series resistances have also been investigated. A four-… Show more

“…This is because power distribution is spread out and unrefined above the charging surface; that is the transfer efficiency is variation when a receiving device position is misaligned, which is deviated from the concentric position with respect to a transmitter [19]. To refine and control the magnetic field by focusing the fields into the small regions, the non-uniform and defected MTSs with modified field localization technique have been proposed [20,25,30,31]. The defected MTS is formed by the cavities on MTS.…”
