Hii Iam in the initial stages of learning MPB tool. My work is mainly focused on band gap tuning. I tried to change the radius every time before I simulate and find the band gap but as Iam dealing with 3-D structures,its consuming a lot of time like 4 to 5 hrs for each simulation to run. Can anybody suggest me a method to find the radius of the triangular lattice photonic crystal for a particular band gap using some kind of a loop???
