N2 - As an emerging electromagnetic device, wireless chargers have gained increasingly attention. In wireless power transfer (WPT) systems, the magnetic coupling mechanism plays an important role. A well-designed coupling structure ensures adequate magnetic coupling while minimizing flux leakage. In recent years, domino WPT has become increasingly popular due to the increased transmission range. Thus, this paper presents a design of a domino conical coil. The magnetic linkage is improved, magnetic field leakage is significantly reduced, and the cost is reduced compared to traditional solenoid domino coils. Additionally, The finite element analysis (FEA) simulation has been developed to verify the structure. The results demonstrate good agreement with the theoretical analysis.
