Abstract: A key to expand the range of waveguide measurement setups for chiral materials is to introduce step discontinuities. Therefore, in this paper the discontinuity of a chiral section of differing diameter in an otherwise empty circular waveguide is analysed by means of a mode‐matching technique. The frequency‐dependent scattering parameters are calculated for some typical constitutive parameters and geometries. The validity of this concept is confirmed by the inversion of these results.
