      Hi,
      I have a grating structure in which each grating teeth is formed by a rectangular waveguide. Is it possible to create sinusoidal structure instead of flat top for the grating teeth.

      Thanks in advance for any suggestions.

      Cheers,
      Anish

      Hi,

      Could you send a basic drawing of your grating (with dimensions), I can try to create a project file for you.

      regards

      Hi Aurelien,

      I have attached a diagram of the structure that I wanted to create. It has dimensions written on it.
      I have also attached OPTI- FTDT file with the structure that I have made for this design.

      Thank you for help.

      Regards,
      Anish

      Hi,

      Sorry for the delay,

      Here is your file slightly modified to include a sinusoidal grating profile. I did it for only one of the gratings, but it could be ported to the others without much problems.

      I hope this helps

      Best regards

      Aurelien
