N2 - In this paper, an analytical formula for the coupling coefficient (k) was introduced for two inductively coupled coils of ring configuration. The response surface methodology (RSM) was used as a tool to develop this formula. The k was tested as a function of the geometrical parameters which include the followings parameters: an air-gap (d) between inductively coupled coils; coils dimensions which include the inner (r1) and outer (r2) radii of the transmitter coil, inner (R1) and outer (R2) radii of the receiver coil; and misalignment parameters. Therefore, the introduced k formula is facilitating of a ring coil design, performance optimization of an IPT system, and prediction of system behaviour at normal or misalignment cases. The percentage effect of each parameter on the k was calculated. It was found that the d has the most considerable impact on the k among other geometrical parameters.
