Hi, I would like to ask about the meaning "num of stacks"? , while it may be self-explanetory, please bare with me as I'm a beginner in this field.
Case 1: If I take an example Superstrate/(AB)^N/Substrate and I set the number of stacks to 10 (N=10), I get a certain reflectivity spectrum.
Case 2 : If I do the oppsite and instead I repeat the layers in the structure window to 10 that is Superstrate/ABABABABAB/Substrate, then I can only get the same spectrum as in Case 1 if I put the number of stacks to 2?? technically speaking in case 2 the number of stacking should be 1 because I have the structure already repeated in the strucutre window. I have tried this approach in a ternary PhC, and it's the same. Does the staking number mean the number of repeated periods or how many materials types your PhC is made of???
