      I tried to use FDTD to find the band structure of a metamaterial (TiO2) which has a zero effective index around 300GHz.

      I took as an example ( and followed all the steps.

      From your result, it seems the propagation vector is not changed during the sweep. Please check the "model" settings, and make sure when k points changes, it can apply to the FDTD and dipole group:

      I guess you create a new project file from new FDTD project file, which has no any script in the "model". I would suggest that you begin with one of the online example file, modify it to fit your need. ALl the online example files have script inside "model".
