N2 - Electromagnetic fields (EMFs) around the wireless power transfer (WPT) coils should be lower than the limits set by standards. In this paper, a design of the WPT coils for a reduced level of leakage magnetic fields (LMFs) and constant efficiency is proposed. A hemicylinder-cylinder joint structure is given. Transmitting coil (TX-C) was wound on a hemicylindrical structure and receiving Rx coil (RX-C) was wound on a cylindrical structure. Thus, the RX-C can rotate around its axis between 0° and 85°. Design procedures are discussed in detail. EMF analysis is investigated under different rotation angles. The chosen design reduced the variation of the mutual inductance (M). Therefore, it maintained a constant power transfer efficiency (PTE) while rotating the RX-C. In addition, LMFs near the WPT windings of the selected design were reduced by 63.6% compared with other coil methods that have similar values of PTE.
