photonics crystal line defect
Has anyone used optiFDTD to get the bandstructure of a triangular lattice photonics crystal with line defect? I have some questions on the setting of the supercells, when I try to get the bandstructure of a photonics crystal without a defect, I set the supercell 1*1, but I mean if I want to cover the defect place, I have to use a bigger supercell, then the results I get are totally different?
Can you guys help me to solve this problem? Thanks a lot~
By the way, if I choose the supercell like the picture shows, does that mean the supercell is 7*1?
