SUMMARY
The discussion focuses on the effective index method for rectangular waveguides, particularly when the width significantly exceeds the thickness. The user seeks clarification on obtaining a y-dependent effective index, starting with the planar waveguide solution. The recommended approach involves solving the planar problem in the x-direction to derive neff(y) and subsequently addressing the y-direction problem. The user contemplates simplifying the process by using the core index from the planar waveguide solution, indicating a need for further understanding of the effective index calculation.
