The propagation properties of strip waveguides are analyzed by a mode-matching technique. Mode coupling, which causes leakage effects, is taken into account in the analysis. The numerical results for the attenuation constants of the first three leaky modes are presented as a function of the strip width. The numerical results obtained by the present method are compared with other theoretical and experimental results. It is found that the higherorder leaky modes have varied and interesting properties, as does the fundamental leaky mode.
