    摘要: The invention relates to phase-shifting cells constituting the passive reflectarrays of antennas with a reconfigurable transmission direction, transmitting in the microwave range. More particularly, the invention describes, within the context of phase-shifting cells of the type having dipole strands angularly distributed in a star configuration, a novel type of switch consisting of a microelectromechanical device essentially comprising a suspended micromembrane which, under the action of an electrostatic force caused by a control voltage, deforms sufficiently to ensure electrical connection between the strands, making it possible to form a dipole in the desired orientation. In one particular embodiment, the micromembrane can be likened to one of the plates of a capacitor and its deformation corresponds to a substantial increase in the capacitance of this capacitor, thus providing the electrical connection. This switch technology has the advantages of greater fabrication simplicity and of enhanced performance compared with the known technologies. The invention provides the main geometrical and technological characteristics for obtaining optimized performance.

    摘要: A method for setting stones in the surface of a jewel produced by electroforming, comprising the following steps: producing a base having external shapes and dimensions with a thickness close to the gold film forming the wall of the jewel to be produced and having seats for receiving the stones; depositing on the base, before setting the stones, a protective coating, then a thin gold film; setting the stones in the seats; then depositing a second thicker gold film; and finally extracting or removing the base and the protective coating. The invention is characterized in that when the base is being produced, at least one passage is provided perpendicular to each seat, capable of communicating, once the stone is set, the space between it and the bottom of its seat with outside, so as to enable the depositing of the second gold film to reach the space. The invention is useful for jewels produced by electroforming.
