Additional information
Open rhombus.pro with Gmsh. The model will automatically compute the band diagram of Figure 3.16, p. 152 of Foundations Of Photonic Crystal Fibres^{[1]}, using a finite element formulation with FloquetBloch conditions^{[2]}. You can doubleclick on any point in the diagram to visualize the corresponding eigenmode, even while the calculation is running.
