As shown, the arrows should point inward rather than outward, with the correct 'bend_radius'. Such a problem does not occur with vertically placed ModeMonitors. ![image](https://github.com/user-attachments/assets/15ddc7e8-8522-4b65-94ef-8035f8d2ed64)

Bug
good first issue

## Problem Modal group index calculations take a while, and cost a lot. That's because they use finite differences. Aside from the cost, it becomes quite problematic to finite difference...

It would be awesome to give `run_batch` a structure of simulations, instead of just a list. This could be as simple as "list of lists" or more featureful like "xarray...

This validator raises an error in 3D simulations when a projection monitor touches periodic/Bloch boundaries. For 2D simulations, we allow periodic boundaries, which won't trigger this error. For 2D with...

as discussed, would be cool if we could evaluate the `simulation.epsilon()` at the design region to get some permittivity distribution to use as the starting value for `invdes` optimization. The...

## Problem When solving for modes in complex dielectric structures, it's common to find a large number of eigenmodes whose eigenvalues are very close together but whose spatial distributions vary...
