Strange PC behaviour changing some parameters
I made the Sample 2—Plane wave simulation based on the periodic cell of PhC of the third tutorial you propose in your Background tutorial. I changed a little bit the initial parameters (basically the initial radius) and I simulated. The graphics that I obtain can be seen in the attached word. In there we can realize that the sum of the reflected and transmited wave is constant: where there is a reflection, there is no transmision, and vice versa. But if I change the wafer material (from air to PBG_atom) and the structure profile (from PBG_atom to air) we can notice that the addition of the reflected and the transmited signals do not sum a constant value. Which is strange and I don’t know why it happens.
Do you know where am I doing something bad?
Thanks a lot,
PD: I attach the file that contains the second case (wafer: PBG_atom and structure: air). Simulations are done in 2D.
