Claim 1:
2. The system of claim 1, wherein the substrate comprises:
a first layer comprising:
a first cutout extending from a top side to a bottom side of the first layer; and
a first spiral trace;
coiled in a first direction about the first cutout; and
defining a first end and a second end; and

a second layer arranged below the first layer and comprising:
a second cutout:
extending from a top side to a bottom side of the second layer; and
arranged in alignment with the first cutout to define the aperture of the substrate; and

a second spiral trace:
coiled in a second direction, opposite the first direction, about the second cutout;
defining a third end and a fourth end, the third end electrically coupled to the second end of the first spiral trace; and
cooperating with the first spiral trace to form the first multi-layer inductor defining a primary axis and a secondary axis.
