Abstract
A transition arrangement for interconnection of waveguide structures or waveguide flanges for forming a waveguide twist, wherein a waveguide twist section arrangement including a number of waveguide twist sections is arranged between the waveguide structures or waveguide flanges for rotating the polarization of waves or signals twisted or forming an angle with an adjacent waveguide flange and/or another adjacent waveguide twist section with respective waveguide openings. The or each twist section on at least one side includes a surface of a conductive material with a periodic or quasi-periodic structure formed by a number of protruding elements allowing waves to pass across a gap between a surface around a waveguide opening to another waveguide opening in a desired direction or waveguide paths, at least in an intended frequency band of operation, and to stop propagation of waves in the gap in other directions.
