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 Floquet-Bloch conditions[2]. You can double-click on any point in the diagram to visualize the corresponding eigenmode, even while the calculation is running.
