Claim 1:
2. The waveguide band-stop filter arrangement according to claim 1, wherein the band-stop filter arrangement further comprises at least one further pair of cavities, where each further pair of cavities is connected to an adjacent pair of cavities that is positioned between the further pair of cavities and the filter interface, where each cavity in a further pair, each further pair cavity, comprises a corresponding inductive further pair aperture arrangement that is adapted to connect the corresponding further pair cavity to a corresponding adjacent cavity via a corresponding common inter-pair wall, where the further pair cavities are positioned adjacent each other along the stacking direction such that they share a further common wall, and where the further pair of cavities comprises a further capacitive aperture arrangement in the further common wall, mutually connecting the further pair cavities.
