| 20080297292 | Radio Frequency Device with Magnetic Element, Method for Making Such a Magnetic Element - A radiofrequency device may include an electrically conducting element associated with at least one continuous magnetic element. The first continuous magnetic element may include a substrate coated with a magnetic film having a granular structure, with grains that are inclined to the normal to the substrate, or a columnar texture inclined to the normal of the substrate. | 12-04-2008 |
| 20080316647 | Miniature Magnetic Core, Sensor Comprising Same and Method for Manufacturing Same - A miniature magnetic core includes at least one bar magnet having, in the demagnetized state, a plurality of magnetic domains separated by magnetic walls, the bar magnet having permanent discontinuities placed at least approximately at the probable locations of at least some of these magnetic walls in the absence of these permanent discontinuities. A miniature sensor includes a miniature core that cooperates with at least one excitation coil and at least one detection coil. A method for manufacturing the magnetic core includes identifying the probable location of the magnetic walls, depositing at least a thin film of magnetic material on a support in order to form the core and producing, in said core, discontinuities approximately at the identified locations of the walls. | 12-25-2008 |
| 20090140384 | PROCESS FOR OBTAINING A THIN, INSULATING, SOFT MAGNETIC FILM OF HIGH MAGNETIZATION, CORRESPONDING FILM AND CORRESPONDING INTEGRATED CIRCUIT - A thin soft magnetic film combines a high magnetization with an insulating character. The film is formed by nitriding Fe-rich ferromagnetic nanograins immersed in an amorphous substrate. A selective oxidation of the amorphous substrate is then performed. The result is a thin, insulating, soft magnetic film of high magnetization. Many types of integrated circuits can be made which include a component using a membrane incorporating the above-mentioned thin film. | 06-04-2009 |
| 20090215207 | Alignment method of two substrates by microcoils - Substrates to be aligned comprise microcoils arranged at the level of their facing surfaces. In an alignment phase, power is supplied to at least the microcoils of the first substrate, whereas the inductance of the microcoils of the second substrate is measured. The microcoils are preferably flat microcoils in the form of a spiral or a serpentine. | 08-27-2009 |

| 20090289747 | MAGNETIC NANO-RESONATOR - A nano-resonator device comprising at least one fixed element and at least one mobile element with respect to the fixed element, first electromagnetic means, integrated or fixed on the fixed element, and second electromagnetic means, integrated or fixed on the mobile element, to generate an oscillating movement of the mobile element. | 11-26-2009 |
| 20100066472 | OPTIMISED SOLENOID WINDING - The inductive micro-device comprises a rectilinear solenoid winding comprising a plurality of disjointed rectangular turns each having predetermined dimensions. At least one of the dimensions of the turns is variable and is determined individually for each turn according to the position of the turn along the winding and to predetermined magnetic characteristics of the winding, in particular a homogeneous magnetic field and/or an optimum quality factor. Said variable dimension of the turns is chosen from the width, length, thickness, height of turn and the value of the gap between two adjacent turns. | 03-18-2010 |
| 20100151797 | RADIO-FREQUENCY DEVICE COMPRISING A THIN FILM WITH HIGH PERMITTIVITY AND PERMEABILITY - A radio-frequency device comprises magneto-dielectric elements. At least one of these elements comprises a composite thin film ( | 06-17-2010 |
| 20110012791 | LEFT HANDED BODY, WAVE GUIDE DEVICE AND ANTENNA USING THIS BODY, MANUFACTURING METHOD FOR THIS BODY - 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. | 01-20-2011 |
