Thanks for your insight.

Are you suggesting that I simulate bandstructure of a unit cell (N times the original one) containing the defect? What should be the x-axis boundary condition (Bloch or PML)? What is the range of kx; [0 - pi/(N*a)] or [0 - pi/a]? 

And then change N till the bandstrcture no longer changes.

Thanks,
