Im trying to find the band diagram for a slab PC with a line defect;

ok, how can i find in mpb software the defect band of the waveguide
without look the localization of the field?
No, a line defect has a genuine band gap below the light cone and
genuine localized modes, and MPB should work fine. (e.g. all of the
examples for slab line defects in our book, http://ab-initio.mit.edu/book
, were computed with MPB.)
(I'm assuming that your line defect has the same periodicity as the
slab. If it has a much longer periodicity, e.g. if you are trying to
model a coupled-cavity waveguide, then the gap is destroyed by band
folding and the modes are leaky; in this case you are probably better
off with Meep.)
