We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

Hi l76124262,

Thank you for the post. You are right that the time variant s-parameter cannot be directly generated from FDTD, and you will need to reformat the data once you get it from the simulations. You can find the time variant s-parameter data format here: https://optics.ansys.com/hc/en-us/articles/360036618513-S-parameter-file-formats. To generate the data for a ring modulator, you can refer to this example: https://optics.ansys.com/hc/en-us/articles/360042322794-Ring-Modulator.Â
