This article gives a study of coupled‐mode analysis for chirowaveguides. Waveguides with chiral material in contact with the perfect electric conducting walls are analyzed with the use of the magnetic‐field‐expansion approach. It is shown that this approach can provide satisfactory results, including propagation constants and field component configurations. Both magnetic‐field‐expansion and magnetic‐induction‐expansion approaches are discussed and compared with each other. Methods of derivation of general expressions of coupling coefficients with the use of the magnetic‐induction‐expansion approach for bianisotropic waveguides are also given in detail. © 1997 John Wiley & Sons, Inc.
