Abstract :
The asymmetric reflectors are unavoidable in the composition of a beam-waveguide feed and generally cause asymmetry of the beam from the feed. By means of the combination of two suitable asymmetric reflectors a rotationally symmetric beam can be obtained on the basis of geometrical optics.
