Abstract
An apparatus for establishing inductive coupling in an electrical circuit arranged on a plurality of dielectric substrates, the substrates being in a substantially abutting relationship and presenting a plurality of substantially parallel planar expanses, includes: (a) at least one first core segment situated in at least one first depression provided in a first planar expanse; (b) at least one second core segment situated in at least one second depression provided in a second planar expanse; (c) a selected second core segment is arranged for establishing magnetic flux coupling with a selected first core segment to establish a magnetic core structure; (d) a plurality of electrically conductive through-hole structures traverse at least one substrate; (e) a plurality of electrically conductive circuit traces are arrayed upon at least two of the planar expanses. The conductive traces and the through-hole structures cooperate to establish inductive coupling.
