In this article calculations of power components transmitted and reflected at the step discontinuities in dielectric‐slab and dielectric‐loaded waveguides are presented using the geometric‐optics approach. Step discontinuities regarding the dielectric slab thickness and refractive index are considered. Numerical results are shown to be in good agreement with those of other rigorous methods. The computation involved in this approach is efficient since the associated mathematical formulation can be analytically expressed from the geometric optics point of view. © 1992 John Wiley & Sons, Inc.
