Reply To: Bandstructure analysis, Hexagonal Photonic crystal

Hi Ankita,

1.The error is most likely because findresonances command wasn't able to find any resonances.This could be due to the modes not being excited strongly enough for them to clearly appear in the spectrum. You can add more dipole sources to see if that helps.

2. For finding the kx and ky for a hexagonal points, you would first have to identify the key points of symmtery. I will see if I can find some references/textbooks that provide the parameters required for kx and ky calculation. In the mean time, by 3D photonic crystal, do you mean a hexagonal 3D arrangement of PCs or a 3D simulation of a planar hexagonal arrangement as shown here: Bandstructure of planar photonic crystal with a hexagonal lattice.
