A radio-frequency device comprises magneto-dielectric elements. At least one of these elements comprises a composite thin film. This film comprises a magnetic material offering permeability above 10 at 1 GHz and a dielectric material offering permittivity above 10 at 1 GHz.

Radio-frequency device comprising a thin film with high permittivity and permeability

This variable-response magnetic radiofrequency device integrated into a substrate comprises:

Variable-response magnetic radiofrequency device

This left-handed substance comprises an array of conductive wires positioned relative to one another in such a way as to present a negative permittivity relative to the electromagnetic waves which have an electrical field parallel to the biggest dimension of these wires and are propagated at a frequency below the electrical plasma frequency of the substance, each wire being made out of a conductive magnetic material having negative permeability for a range of frequencies of the electromagnetic waves below the electrical plasma frequency of the substance and when there is no external artificial static magnetic field. Each wire comprises at least one strip, made out of a conductive magnetic material that extends along the greatest dimension of the wire in a plane of the strip and has a thickness at least twice as small as the skin thickness of the conductive magnetic material.
