Abstract :
The property of multi-aperture irises to cause the rejection phenomena because of the interaction of two or more "iris aperture" eigen oscillations is used to propose the simplest rejection section in a circular waveguide. As an iris limiting case the set of narrow azimuth-placed arc-shaped slots with a large central aperture has been studied. Saving the low insertion loss near the stopband frequency these sections can reject the TE11 and TM01 modes totally and partially the other ones.
