FILM MAGNETIC STRUCTURE FOR ELECTRICALLY CONTROLLED UHF DEVICES Russian patent published in 2016 - IPC H01F10/12 G11C11/14 

FIELD: electricity.

SUBSTANCE: structure contains thin film metal ferromagnetic layers, each of them is separated from the adjacent layer by a nonmagnetic dielectric layer. All the thin film metal ferromagnetic layers are divided to multiple electrically insulated areas, their dimensions are below one eighth of the length of the electromagnetic wave in the layer of the nonmagnetic dielectric.

EFFECT: increased activity of the film magnetic structure, ie its ability to change its HF effective magnetic permeability under the action of an external control magnetic field.
