The cutoff frequencies of higher order modes in a symmetrical strip line are calculated using the variational finite‐element method combined with conformal mapping. Conformal mapping is used to improve the modeling of the infinite transverse extents of a strip line. Then the finite‐element method is employed to solve the variational equation in the transformed finite region. Comparisons with numerical results found in the literature validate the presented method. © 2002 Wiley Periodicals, Inc. Microwave Opt Technol Lett 32: 449–452, 2002.
