The Simplest Notch Rejection Sections in the Circular Waveguide

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-shape...

Description
Summary: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 TE 11 and TM 01 modes totally and partially the other ones.
