Is applicable to waveguides which can propagate two orthogonal polarizations of the same waveguide mode. In this way, the waveguide type is generally restricted to square or circular cross-section, such as waveguide with an octagonal cross-section. The objective of the three test procedures given below is to characterize the cross-polar properties of waveguides. When a single mode of defined polarization is generated at the source ent of the waveguide under test, geometrical imperfections will induce a depolarization to occur as the signal propagates along the waveguide. This dapolarization will be a limiting factor on the usefulness of the waveguide in supporting two independent polarizations.
