  • Device for revealing spatial variations in the polarisation of electromagnetic radiation
    Patent number: 11959953
    Abstract: A device is suitable for revealing spatial variations in polarization of an electromagnetic radiation, in a form of localized temperature variations. The device includes a surface of a carrier which is electrically and thermally insulating, and includes an array of patterns which each consist of at least one rectilinear segment of a sensitive material, of which the orientation is variable within each pattern or between neighboring patterns. Such device may be used with a thermal camera to reveal, in infrared images, temperature variations which are localized at segments not perpendicular to a local direction of linear polarization of the radiation.

  • Compact helical antenna with a sinusoidal profile modulating a fractal pattern
    Patent number: 9698474
    Abstract: The invention concerns a helical antenna comprising a shape of revolution and a plurality of radiating strands helically wound around the shape of revolution, characterized in that each radiating strand is defined by a repetition of a fractal pattern comprising segments formed by a sinusoidal curve.
