CA 2244956

The invention concerns an electromagnetic high-frequency or microwave apparatus comprising a treatment chamber (6) with a transfer wall (7, 7', 7") which allows electromagnetic waves to pass through to an adjacent chamber (4) and is designed to influence the intensity distribution of the transfer of the electromagnetic waves into the treatment chamber (6). The apparatus according to the invention enables the intensity of the transferred waves to be controlled with low losses in that the transfer wall (7, 7', 7") comprises a plurality of rod-shaped antenna elements (10, 10') oriented at an angle to the plane of the wall of the adjacent chamber (4), the antenna elements (10, 10') projecting centrally through through-openings (14, 14') delimited by electrically conductive material.

L'invention concerne un appareil électromagnétique à haute fréquence ou à micro-ondes qui comprend une chambre de traitement (6) séparée d'une chambre (4) adjacente par une paroi de transmission (7, 7', 7") perméable aux ondes électromagnétiques, ladite paroi de transmission (7, 7', 7") se présentant de manière à influer sur la répartition de l'intensité de la transmission des ondes électromagnétiques dans la chambre de traitement (6). Cet appareil permet une régulation à faibles pertes de l'intensité des ondes transmises, du fait que la paroi de transmission (7, 7', 7") présente une pluralité d'éléments d'antenne (10, 10') en forme de tiges, orientés de manière angulaire par rapport au plan de la paroi de la chambre adjacente (4). Ces éléments d'antenne (10, 10') font saillie de manière centrée à travers des orifices de passage (14, 14') délimités par un matériau électro-conducteur.
