I am trying to calculate how the duty cycle of the grating affects the reflection and transmission profiles. And I am getting wrong results. The attached code is the EME setup, please help me to identify what is wrong with the simulation.  I am trying to sweep the duty cycle of the grating for 1000 periods and plot the transmission versus the duty cycle sweep. I have selected the conserve energy method and when doing so I can see that maximum peak is at 0.5 duty cycle.  But when turning off the conserve energy I get a plot like this. I want to do make passive because I want to see at which length the transmission becomes 0.<\/p>\n

<\/p>\n

And when the conservation of energy is setup the plot is as follows. <\/p>\n

<\/p>\n

I was expecting to see a similar plot with the “make passive” option on. <\/p>\n

I have tried mode convergence sweep to see where the profile gets stable, I tried different meshings, and setting up cells differently. But the results are still confusing. Can you please help me to identify the problem ?<\/p>\n

I have also attached the script. In the link below.<\/p>\n
