I know sent the supercell with no defect to calculate slab mode.
But how to project it to the waveguide direction?
Just plot it as a function of the waveguide-parallel k vector.
The only thing you need to be careful of is to arrange your supercell so
Dear Prof.Steven and others,
Thank you for your answer.
But my question is how to set the K path in calculating and
projecting the slab mode?
You known, projecting the slab mode needs to scan the full area
of Brillouin zone, then project to the waveguide direction.
Below is my
The easiest way to project the slab modes for a line defect is just to use
a large supercell with no defect.

Dear Prof.Steven,
Thank you for your instant reply.
I am sorry that I can't understand you.

Just a large supercell is enough? why? Could you please talk into

Prof.steven and other MPB user:
In the case of line defect waveguide in photonic crystal slab,I succeed in
caculating the waveguide mode with MPB.but there still something left:I must
find way to project the band strucure of the regular lattice of the
slab(slab mode) and the lightcone?You can
