Defining the Y axis/plane

I have a question regarding fixing the Y-axis using OptiFDTD. While we simulate, the structure is infintely long in Y-direction but finite in Z & X-direction, but can we make the Y-direction finite for any device using the software? However it’s known to me that Z & X-direction dimensions can be specified and defined.

Thanking You,
Sourav

      The domain of FDTD is always finite, which is why there always needs to be boundary conditions! What you are getting at is the difference between a 2D and 3D simulation. In a 2D simulation there will be no y dimensions. Simply giving profiles a thickness and choosing a 3D simulation will let you set the options.

      Cheers!
