1. A patterned magnetic core comprising:
a first sub-core; and
at least one second sub-core, wherein the first and second sub-cores are spaced apart by a gap, wherein each of the first and second sub-cores has a width less than or equal to a threshold width based on an operating frequency of the patterned magnetic core and wherein each of the first and second sub-cores comprises:
a plurality of magnetic layers; and
a plurality of interlamination layers disposed between the magnetic layers in an alternating fashion.
