  Hello
  I want to simulate an Add-drop microring resonator in the MODE module and get the results of the S parameters. I can not use the FDTD module due to lack of hardware.
  How to calculate S in the MODE module? Does it have a script? If the answer is yes, please guide the exact script.
  Thanks.

  Do you want to get the S parameters for the whole device (buses + resonator)? and what is the next usage of the result? If I know this, I could give you more direct answer.
  You can use varFDTD: https://support.lumerical.com/hc/en-us/articles/360042800233-Ring-resonator-getting-started-Parameter-extraction-and-Monte-Carlo

  If it is later used in INTERCONNECT, you do not need to simulate the whole device: https://support.lumerical.com/hc/en-us/articles/360042323794
