A variational method involving the transverse components of the electric field and their transverse derivatives has been used to calculate the dispersion curves of the higher‐order modes of an electromagnetic wave propagating along a lossless rectangular chirowaveguide with perfectly conducting walls. The agreement between the variational results and those obtained by a finite‐difference method is excellent for the dominant mode, but deteriorates for higher‐order modes. The chirowaveguide modes have been labeled, and their cut‐off frequencies have been given as functions of the ratio of the guide dimensions. © 1996 John Wiley & Sons, Inc.
