Abstract
A magnetic structure having improved permeability characteristics at very high frequencies and comprising a plurality of magnetic metal layers, together with electrically insulating layers which are interposed between successive magnetic metal layers to form a laminate therewith, and at least one conductive strip electrically connecting together at least two of the magnetic metal layers, the conductive strip being of lesser width than the surface on which it is located, and serving to reduce eddy current losses.
Claims3
A magnetic structure having improved permeability characteristics at high frequencies comprising:
- a plurality of magnetic metal layers,
- an electrically insulating layer interposed between successive magnetic metal layers to form a laminate therewith, and
- a plurality of electrical conductive strips each electrically connecting together at least two of said magnetic metal layers, said strips each having a width less than the width of the surface on which they are located, and being electrically isolated from each other.
