  • Patent number: 10103006
    Abstract: An elementary device of the present disclosure includes a coaxial applicator that includes a connector disposed at a distal end of the applicator, a shielding, a microwave energy propagation medium disposed between a central core and the shielding, and an insulating body disposed at a proximal end of the applicator. The shielding surrounds the central core and has a bottom wall provided at the distal end. The connector includes an external conductor connected to the shielding and an internal conductor connected to the central core. The connector is disposed at the bottom wall with the external conductor fixed to the bottom wall and the internal conductor linked to a connecting element that extends through the bottom wall and parallel to the main axis with a predefined spacing provided between the central core and a free end connected to the central core at a predefined distance from the bottom wall.

  • Publication number: 20180261433
    Abstract: The present disclosure relates to an elementary device for producing a plasma. The elementary device includes a coaxial applicator of microwave power that includes a conductive central core, a conductive external shield surrounding the central core, a medium located between the central core and the shield to propagate microwave energy, and an insulating body. The elementary device further includes a system to couple to a microwave generator and is disposed at the shield. The shield has a proximal end plugged with the insulating body made of dielectric material that is transparent to the microwave energy. The insulating body has an external surface configured to contact and excite a gas located in the interior of a chamber. The insulating body extends exterior wise from the shield and its external surface is nonplanar and protrudes from the shield. The outside diameter of the body decreases from the shield to its tip.

  • Patent number: 8758696
    Abstract: The device for electromagnetic radiation treatment of a reactive medium includes an electromagnetic radiation generator, a reactor containing the reactive medium, and a device for transmitting the electromagnetic radiation generated by the generator to the reactive medium contained in the reactor. The device includes a wave guide for transmitting the electromagnetic radiation from the generator and a coupling means arranged to allow transfer within the reactive medium of the electromagnetic energy transmitted by the wave guide. The wave guide includes a curved segment in a general ā€œUā€ shape forming a return loop from the wave guide. The device further includes a separation wall that isolates the generator form the reactor, with the reactor being connected to the curved segment. The curved segment extends at least partially from one side of the separation wall to the opposite generator.

  • Patent number: 8759074
    Abstract: The invention relates to a device (7) for applying electromagnetic energy to a reactive medium, with said device being designed to be connected to an electromagnetic radiation generator using a means of transmission (4) of said radiation, with the device being remarkable in that it includes at least one loss transmission line (70) that features an interface that transfers electromagnetic energy towards the reactive medium, with said transfer interface being arranged so as to assure, throughout the length of the said line, a pre-determined distribution cross-section for the density of the electromagnetic energy delivered to said medium by said line. The invention also relates to a device for processing, by electromagnetic radiation, of a reactive medium including such an application device. The present invention can be applied to the sector of devices for thermal treatment of a reactive medium, specifically by microwave or high-frequency radiation.
