Plasmonic waveguide example #161

Very thorough example that could be interesting to reproduce

This is a good example for FEM / refinement since the mode is highly localized

wow, so many graphs to reproduce! sounds great!

I was able to implemented a plasmonic slot waveguide with an accuracy of 1e-4 ~ 1e-5 for Real(n_eff) compared to a commercial photonic solver under almost similar conditions (differences were: use of PML BC and rectangular mesh elements).

Are there any examples of using PML BC with metals touching the boundaries? Without this, I would need to use larger simulation box and/or a finer mesh, for better accuracy, which my PC seems to struggle with.
