I want to calculate the band structure of 2D periodical

many flat bands which are not exist in the results calculated by
multiple scattering method. Although I change the frequency
bandwidth, the resolution, the time step, the results have no
change. Can someone tell me what happens? The ctl file for
calculation is attached. Thanks in advance!
This is what I suggest whenever you are confused by the output of
harminv:
Run another simulation with a narrow-band source centered at the
frequency (and, in your case, k point) of interest. This will excite
just that mode (if it is real). Then you can look at the field
pattern and figure out what it means, physically.
