      I want to know what is the S-Parameter used for?
      Such as to calculate the transmission ratio of a waveguide?

      Zejun,

      The S-Parameters provides a relationship between the input and output signals at all of the ports for your structure. The ports are identified as the ports you create in the design. You can find a full write up on their derivation and use in the “Technical Background” in the help document that came installed in your product. Open OptiFDTD, click on help->help topics and from the web page that opens select “Technical Background”.

      Scott
