Abstract

We discuss a simple, self-consistent iterative method for the analysis of rectangular waveguides with strong guidance. We show that this method removes the ambiguity of the conventional effective index method and gives a convergent value of the propagation constant both near and far from cutoff. Near the cut-off region, the accuracy can be improved by including an external effective index correction which takes into account the finite mode effect outside the waveguide.
