In the case of specifying material's complex dielectric permittivity using a tabulated data, what should the format be? I created a material file as follow with guidance from scuff-em documentation which I named it Graphene.txt. The left column is frequency and the right one is the corresponding complex permittivity.
Dear Homer Reid,
In the case of specifying material's complex dielectric permittivity using a tabulated data, what should the format be? I created a material file as follow with guidance from scuff-em documentation which I named it Graphene.txt. The left column is frequency and the right one is the corresponding complex permittivity.

However, I got this error message when I try to run scuff-cas3D:
error: no imaginary-frequency data given in material data file /home/hooi0004/scuff-em-installation/share/scuff-em/examples/Graphene.txt (aborting)
Looking forward to your advice. Thank you so much.
