| abstract |
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. |
