The present invention relates to a wave choke system for a door of a microwave oven. The wave choke system comprises at least one wave trap (10) formed as an elongated channel and bordered by four channel walls (22, 24, 32, 34) made of one or more conductive materials and by at least one gap (28). The wave trap (10) is provided for extending at least partially along a door frame and/or along a cavity frame (12). The wave trap (10) comprises at least two adjoining wave choke recesses (14, 16) for a λ/4 transformation parallel to each other and parallel to the wave trap (10). Two neighbouring wave choke recesses (14, 16) are separated by an elongated wave barrier (18) made of one or more conductive materials. The height of the wave barrier (18) is lower than the height of the wave trap (10). |
