We report the first study of three‐dimensional (3‐D) discontinuities in chirowaveguides. The multimode coupled‐mode method is an effective numerical approach to analyze this problem. After obtaining the coupled‐mode equations, we diagonalize the coupling matrix to obtain a multimode scattering matrix rather than the usual two‐mode approximation. Excellent agreement is found when we compare our results with experimental data for the achiral case. Numerical results are displayed to demonstrate the usefulness of our approach, and to examine the effects of the chirality admittance on scattering properties. We find that the sensitivity of the scattering parameters to chirality admittance increases as the chirality admittance increases. © 1997 John Wiley & Sons, Inc.
