@elizaleung830 Thanks!

I've implemented the effective area (for $E_x$ / $E_y$ and $E_{xy}$) and tweaked the example a little.

Could you have a look if we need to adjust the resolution a bit more to converge with the numbers from the paper better?

Would also be great to have graphs for the other examples they provided in the paper, should just be an extra loop as you added already the data :)
We could also add the mode_transversality from the paper, that should be fraction_tm of the mode :)

After that the new example should be ready to go to the docs 🥳

Yes sure! I have added another graph as well as the mode transversality. However the tm_fraction doesn't seems to fit the data in paper very well, this might because of the slightly different defnition in the paper?

The resolution for neff and aeff in the code look good to me. However i realised that i probably need equation 1 and 2 as I will do some stimulations on waveguide as well. Would it be possible to implment them as well?

Thanks a lot!
