Abstract (en)

[origin: WO8304457A1] A structure comprises a cascade of cylindrical cavities having a double resonance mode; each cavity (e.g. 100) is coupled to the adjacent cavity (e.g. 200) by a coupling iris (400) orientated in a direction offset by a predetermined angle ( theta ) with respect to the angular position of the tunning screws (1, 2) of the cavity (100) while the adjacent cavity (200) is offset by a predetermined angle ( psi ) with respect to the angular position of the coupling iris (400) which couples it to the first cavity (100).
