Dear Amrita,

Thank you very much for your answer and reproducing my simulation.

You wrote that a plane wave source should not be used to inject a mode into a slab waveguide. My follow-up questions are:

  • How would you recommend to inject a mode into a slab waveguide with Bloch periodic boundary conditions? To the best of my knowledge, the mode source does not support Bloch boundary conditions.
  • If it is not possible to perform a simulation as described above, how would you set up a simulation to measure the transmission through an (infinitely) wide waveguide slab containing a height discontinuity?

I am looking forward to your thoughts.
