This commit update `demo_axis.py` with a version working for different `theta` and sphere radii. However, there are some weird artifacts in the field, and the degree of the phi component of the electric field needs to be smaller than 3, otherwise the correct solutions is not reached.

@mikics This is still marked as a draft, could you comment on what still needs doing? |
I need to change the post-processing of the single component of the electric field, and to fix a few typos in the formula I implemented. Will do it in the next days! |
This should fix the failing of the CI check for the Red Hat clone, that probably does not have ADIOS installed.

Currently, there are no demos showing how to solve axisymmetric electromagnetic problems. This pull request adds a demo for showing how to solve a simple problem of such kind: a metallic sphere hit by a plane wave (with axisymmetric PML condition). By exploiting the cylindrical expansion for a plane wave, we can split the full 3D problems into few 2D problems, with an overall significantly lower computational cost.
