Electromagnetic fields inside circular, tuned corrugated waveguides, also called soft‐ and hard‐surface waveguides, are considered. The waveguides are filled with chiral material. The propagating eigenfields are presented. In this paper, a recently studied case with small chirality parameter values is generalized. Also, reflected and transmitted fields are considered. It is shown that the chiral soft‐ and hard‐surface waveguide section of a proper length can be used as a mode transformer between TE and TM modes. This kind of waveguide component may be used as a matching element between different kinds of circular waveguides and antenna elements. © 2002 John Wiley & Sons, Inc.
