Unfortunately no, legume currently only accepts real permittivity. There are various complications with lossy modes, specifically with properly ortho normalizing the basis set.
I think what you may have seen as complex is the Fourier transform of the permittivity. For a real valued field this is still complex, but has the property that e(G) = e(-G)*

Thank you for your reply!
What I want to do is to calculate the band stucture of a PhC slab with loss, which means the permittivity has imagniary part. I will find other ways to do ti.Thank you again.
