  I am simulating a grating for testing the reflection and transmission behavior.
  When I try to set DFT Spectrum – in the Simulation section this appears hidden.
  I am using the trial version for 30 days.
  Can someone help me ?

  Hello Giusy,
  
  The most likely explanation would be that your source is set to be Continuous-Wave (CW). If it is CW there is only one wavelength so the DFT spectrum option is not available. Can you confirm this is the case?
