ABSTRACT:
The polarizer with a circular waveguide in the inner wall of which are formed identical circular corrugations positioned in a plane perpendicular to the longitudinal axis XX of the guide. The corrugations have four quadrants: a first pair of quadrants opposed by the apex in which the depth of the corrugations is less than in the second pair. By positioning the waveguide in such a way that the incident field E is parallel to the limit between two adjacent quadrants, the phase velocity of the orthogonal components C.sub.1, C.sub.2 of field E is dependent respectively on the admittance of the quadrants of the first pair and the quadrants of the second pair. This leads to a phase difference at the polarizer outlet and the corrugations are defined so that this difference is substantially 90.degree..
