A point-to-point wireless power transfer coil coupling model and a point-to-point wireless power transfer system. The point-to-point wireless power transfer coil coupling model comprises a transmit ring resonator and a receive ring resonator. The transmit ring resonator and the receive ring resonator in the point-to-point wireless power transfer coil coupling model are coupled to each other, and the resonant frequency of the transmit ring resonator is the same as that of the receive ring resonator, i.e., the transmit ring resonator and the receive ring resonator are in a magnetic resonance state; moreover, the transmit ring resonator and the receive ring resonator that are in a magnetic resonance state can improve the transmission efficiency during a wireless power transfer process.
