Sinusoidal grating structure

[Anish LamichhaneParticipant]

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.

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
