  • 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.
