Re: [Meep-discuss] A strange result of trans. and refl. calculation

Since you are modeling a flat/planar structure, you will need to use a 1d computational cell. The 2d cell you are using is a supercell which introduces unwanted additional modes due to band folding (for more details, see Section 4.6 of our book chapter ). Note

[Meep-discuss] A strange result of trans. and refl. calculation

Hello meep users, I tried to calculate the transmittance and reflectance of glass (eps=2.25). However, the result was strange; the resulting transmittance and reflectance were fluctuated according to the frequency as the figure in the link below.
