To simulate periodic structures efficiently, Floquet's theorem is applied to a compact finite‐difference method for the analysis of dispersion characteristics of general periodic guided wave structures. By solving the full‐field‐component Eigen equations, dispersion characteristics and modes are obtained. The proposed method shows good applicability to the periodic guided structures where complex mode pairs, radiation modes, or leaky modes, etc., may exist. © 2008 Wiley Periodicals, Inc.
