Reply To: Bandstructure and dipole_cloud analysis group

Sorry about the broken link. I would recommend the photonic crystal examples for a demonstration of how to use these analysis groups:
This example might be helpful as well, it uses the same approach for a surface plasmon dispersion relation calculation:
Your simulation should be similar to the SPR example, you will just have to be careful to make the periodicity of the simulation match the periodicity of your grating. Please let me know if you have any questions.
