We also derive explicit expressions for the effective group index and the effects of external forces on the propagation constant. Furthermore, with our method the phenomenon of avoided crossing of modes is observed and studied.

The results of this method are compared with those of the effective-index method. Our results are generally in good agreement with results of other rigorous approxim 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 idea of the method is to replace a rectangular-core waveguide by an equivalent slab waveguide with an effective refractive index calculated from another slab waveguide. Because the method is easy to implement and fast to execute, it has been used widely for solving waveguide problems over the years [2], [3]. Effective-Index Method. • Effective-index method appropriate when thickness of a rectangular waveguide is much smaller than its width (d ? w). • Planar waveguide problem in the x direction is solved first to obtain the effective mode index ne(y). • ne is a function of y because of a finite waveguide width. • In the y direction, 24 Sep 2011 Is anyone familiar with the effective index method for rectangular waveguides? I have a waveguide for which the width is much greater than the thickness. I think I need to start by treating it as a planar waveguide. But I am supposed to get an effective index which depends on the y coordinate. I know how to Two different approximations for the propagation constant of a guided mode in a rectangular dielectric waveguide can be obtained by applying the conventional effective-index method to the waveguide in two different ways.
