We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

When i adjusted the kx for fundamental mode (0.25 to 0.45), the index i am getting is 2.08807 where as in the eigen solver of the source is 2.81, even if i adjust the values to a smaller range.. how do i get the effective index of first order mode ( the second TE mode from the user selct option in the source)? When i adjust the range  of kx in the sweep , i am getting the value of substrate effective index? should i use the same kx value or should i adjust the kx value in this case?
