Abstract: An orthomode junction for separating and/or combining orthogonally-polarized radiofrequency wave signals, comprises a body which has a main cavity forming a main waveguide, which has a blind end, and auxiliary cavities forming auxiliary waveguides, which communicate laterally with the main cavity in the vicinity of the blind end thereof, and a deflection insert situated at the blind end of the main cavity and facing the auxiliary cavities, the deflection insert having different shapes on the side of the auxiliary cavities respectively.

Abstract: Disclosed is an assembly for the propagation of waves of frequencies between 1 GHz and 10 THz, including: (a) a waveguide to guide the waves, the waveguide being produced from a plastic material, a part of the waves propagating inside this waveguide and another part of the waves propagating outside this waveguide; and (b) a protective covering which surrounds the waveguide delimiting one or more spaces between the waveguide and the covering, in which space or spaces the waves propagating outside the waveguide are contained, the protective covering thus forming a barrier to protect these waves from external disturbances.
