Abstract (en)

[origin: EP2509152A2] The arrangement has two cavity resonators coupled by a common pot wall (4). A coupling window (5) is completely enclosed by an electrically conductive material (6). A coupling unit (7) with a variably adjustable capacitance is inserted in the window. An electrically conductive bar element (8) is electrically conductively connected with the material by bar element ends (10, 11) on both sides. Finger elements (12, 13) are fastened at the bar element for electrically insulating the bar element so that the finger elements are rotatably mounted around a rotational axis coinciding a bar axis (9). An independent claim is also included for a method for varying an electromagnetic coupling strength between the two cavity resonators.
