Graphene
Due to graphene hype, I have decided to check if COMSOL can handle graphene.
Meshing has to be sufficiently high, but also do not introduce too high meshing density gradients in your geometry.
In the following examples, I used 10 meshing ellements accros the graphene thickness, and the calculated transmission as function of wavelength is calculated in 2D. In 3D I have tried for graphene bi-layer only.
This is very good example, since the opticall properties of graphene are well documented, and the absorbtion of graphene is around 2.3% per layer..

Note that meshing in 3D was finer, and the obtain solution does't oscillate (red stars) as in case of 2D (black squares).
The model should be easy to build, if you followed this site's materials.
