17 and Eq. 15-3 gives three quadratic equations for x, y, and z. 3 G DISTANCES One more distortion is caused by the distance between the coil’s wires in the same common G factor. We assume that the current in two coils flows in the same wire with a common G factor. But really the thickness of the PCB is a distance between the coils, so there is no common G. After minimization of the PCB thickness, we add two layers in a Sandwich pattern. 2. We show the improvement. 66 Mordechay Esh r r Coil 2 Coil 1 2d Coil 1 2d Coil 1 2d 2d Coil 1 Coil 2 Fig.
