Since bandstructure simulaiton needs Bloch boundary condition and DGTD has not implemented, please try to use FDTD instead.
Not sure what do you mean "perturbation" here: anything that breaks the periodicity will not be considered as "periodic">
For band structure edge, you can specify the correct K value, for example at the edge of symmatric point Km. You still need to simulate the band structure. YOu may also use the transmission band to find the bandgap.eg, T vs frequency.
