Abstract

A polarizing screen comprises an arrangement of at least one, electrically conductive, polarizing cell (112), which at least one cell is frequency- and polarization- selective, for transforming the polarization of the electric component E of the transverse electromagnetic (TEM) wave, received with linear polarization, into an electromagnetic wave with circular polarization. The four lateral walls (124, 125, 126, 127) of each section of waveguide (120) forming a polarizing cell (112) are each open over their entire length due to a median continuous slot (134, 135, 136, 137), parallel to the direction of propagation of the incident electromagnetic wave, so as to form four angled electrically conductive plates. Each polarizing cell (112) includes electrically conductive interconnection rods which interconnect the lateral walls and the four angled plates so that they are partially or completely rigidly connected and which form one or more electrical discontinuities (152), which are arranged at the ends of or inside the section of waveguide forming the polarizing cell and form one or more inductive or capacitive loads, or one or more (LC) resonators equivalent to an inductor and a capacitor connected in parallel or in series. The longitudinally open slots of the lateral walls and the elementary electrical discontinuities of each polarizing cell include geometric shapes and dimensions which provide total transmission of the incident wave, which is associated with a phase anisotropy of +90° or -90° according to the components E V and E H.

Abstract

A radiating phase-shifting cell is designed to favour the excitation of an equivalent resonance of the “slot” type in a first part of the phase cycle, and to favour an equivalent resonance of the “microstrip” type in a second part of the phase cycle. This property notably allows the bandwidth of the phase-shifting cells to be optimized. A phase range of 360° can in effect be segmented into two sub-ranges of around 180°. This segmentation into two sub-ranges is made possible by the complementarity of the resonant modes of the slot or microstrip type. The radiating phase-shifting cell is notably applicable to reflector arrays for an antenna designed to be installed on a space craft such as a telecommunications satellite or on a terrestrial terminal for satellite telecommunications or broadcasting systems.

Abstract

Process for labelling a material based on at least one organic thermoplastic or thermosetting polymer matrix comprising a step that comprises incorporating therein, by dispersion during its manufacture or its formation, at least one compound based on at least one photoluminescent rare earth in a concentration that renders this compound detectable under UV irradiation, wherein said compound is a coordination polymer that is in the form of a crystallite obtained by reaction of at least one photoluminescent rare-earth ion with at least one unsaturated organic ligand.

Abstract

The present invention relates to a method for marking at least one material comprising a non-organic matrix, characterised in that it comprises at least one step that involves incorporating in said material during the production thereof at least one compound containing at least one luminescent lanthanide in a concentration such that said compound in said material can be detected under UV radiation, wherein said compound is a co-ordination polymer in the form of a crystallite obtained by reacting at least one luminescent lanthanide ion with at least one unsaturated organic binder.
