Continuing discussion from: Fail to find a bandgap for 1-d PC cavity
Sry for late…After changing the symmetry, I get the result as paper
mentioned. Thank you for your reply and suggestion.
But now I encountered another question when I do other simulation:
This is a really big model, I want to see how much power can be coupled
into the fiber: the fiber’s dimensions are R:62.5um r:1.5um L:80um
the mesh size is 10001000300 . After calculation, I got two plots about
the power, but as you see, there are too many zigzags on plot.
I want to know what can cause that and how to cancel it. Thanks for your
