1) Lateral misalignment: In this case the pair of Tx and Rx coils are situated in parallel planes,
which are separated by a vertical distance d and their centers are displaced by a lateral distance
l, as shown in Fig. 3(a).
2) Angular misalignment: In this case the plane of the Tx coil is tilted to form an angle µ and
the axis of one coil passes through the center of the other coil, as shown in Fig. 3(b).
3) Incorporated misalignment: This case incorporates both lateral displacement and angular tilt
of the coils, as shown in Fig. 3(c).
