A wireless power transfer apparatus 100 includes at least one non-planar flux coupling structure 112. The non-planar flux coupling structure comprises a first set of coil portions 114 spaced along a first axis (Fig.10, A1) and a second set of coil portions 116 spaced along a second axis (Fig.10, B1). The first and second sets of coil portions, which may be arcuate, are at least partially disposed in or on a curved or non-planar surface 118, and the first and second axes are tilted at opposite angles (Fig.10, α1, β1); the angles may be equal and about 45 degrees. The non-planar flux coupling structure may be a flux receiver and the apparatus may further include a planar or non-planar flux transmitter (Fig.3, 15). Additionally, a magnetic structure (Fig.17, 401, 402) may be positioned inside or outside one of the coil portions to facilitate inductive coupling. The first and second coil portions may be part of a first coil (Fig.13, 212) and a second coil (Fig.13, 213), respectively, and the first and second coils may include a set of coil portions disposed in or on a flat surface.
