N2 - Efficient wireless power transfer (WPT) systems seamlessly integrated with electric vehicles (EVs) are crucial to their successful massive rollout. This paper proposes a WPT system with a high-permittivity metasurface integrated with a wheel for efficiency enhancement. The single-turn coils with coupling-enhanced rings are explored as transmitter (Tx) and receiver (Rx). The metasurface is composed of high-permittivity elements placed on both surfaces. The symmetric system model ensures bidirectional transmission between EVs and power grids. With the aid of the metasurface, the efficiency of the WPT system is substantially enhanced and maintained within 400 mm.
