Abstract: Leaky wave antenna of AFSIW structure comprising a top substrate layer and a bottom substrate layer sandwiching an intermediate layer comprising a longitudinal aperture of length L defining a waveguide and whose width W1 is delimited by two conductive lateral walls. The inner faces of the conductive lateral walls are coated with a layer of dielectric material of thickness w(z). The top layer has a longitudinal radiating slot of width Wf (z) facing the longitudinal aperture of the intermediate layer. The thickness w(z) of the dielectric coating varies along the longitudinal axis z according to a given law, defined so as to obtain variations along the axis z of the amplitude Alpha(z) and of the phase Beta(z) of the leaky wave of the guide.

Abstract: Disclosed is an assembly for the propagation of waves of frequencies between 1 GHz and 10 THz, including: (a) a waveguide to guide the waves, the waveguide being produced from a plastic material, a part of the waves propagating inside this waveguide and another part of the waves propagating outside this waveguide; and (b) a protective covering which surrounds the waveguide delimiting one or more spaces between the waveguide and the covering, in which space or spaces the waves propagating outside the waveguide are contained, the protective covering thus forming a barrier to protect these waves from external disturbances.

Abstract: A process including introducing, into a device, an aqueous fluid containing at least one inorganic salt, the water of the aqueous fluid being in supercritical conditions or close to the supercritical range in the device, and measuring the concentration or the amount of inorganic salt in the device, this measurement preferably being carried out before the entry of the inorganic salt into the device, Then bringing the inorganic salt into contact with an aqueous flow containing at least one hydroxide salt to obtain in the device an aqueous fluid mixture containing an inorganic salt and a hydroxide salt and adjusting the concentration or amount of the hydroxide salt as a function of the concentration or amount of the inorganic salt needed to at least partially solubilize the inorganic salt. Preferably the measurement of the concentration or the amount of inorganic salt leaving the device is also performed.

Abstract: According to one aspect, the subject of the present description is a device (100) for determining characteristic parameters of the dimensions of nanoparticles in suspension in a liquid. The device (100) comprises light-emitting means (101) configured to emit an incident light beam (Bi) that is linearly polarized along a polarization axis (P1); a detecting unit (102) comprising a measurement arm (120) that is rotatable with respect to an axis of rotation (Δ), said detecting unit comprising first and second detection channels (151, 161) that are separated by a polarization-splitting element (125) arranged in said measurement arm; a fixed sample holder (103), configured to receive a container (10) of cylindrical symmetry of said sample, an axis of symmetry of the container being coincident with the axis of rotation of the measurement arm; and a control unit (104). The polarization-splitting element (125) of the measurement arm is configured to simultaneously send, over each of the first and second detection channels, respectively, a first and second polarized component (BS1, BS2) of the beam (BS) scattered by the sample, the polarization axes of the first and second polarized components being perpendicular.
The control unit (104) is configured to determine, from signals corresponding to the polarized components detected in each of the detection channels as a function of time, at least two characteristic parameters of the dimensions of the nanoparticles.-

Abstract: A method is provided for controlling the matching of an antenna to a transmission path. The transmission path includes an amplifier stage coupled at an input or at an output to the antenna and to a resistive load. The method includes performing a checking phase by measuring a first current temperature at or in proximity of the antenna and a second current temperature at or in proximity of the resistive load, triggering a matching of the impedance seen at the input or at the output of the amplifier stage in the presence of a first condition involving the first and second current temperatures, and then stopping the matching of the impedance in the presence of a second condition involving the second current temperature.
