Abstract :
The scattering of the even TE guided modes incident on a step discontinuity in a planner dielectric waveguide is analysed by means of a novel integral formulation. An accurate numerical solution is obtained from an iterative procedure needing a successive order of approximation in the scattering mechanism.
