The field profile monitors are represented as a box in the beginning.So how should we set them(as a line, as a rectangle or as square) so as to get transmission,reflection?
If you go to the Edit tab of the DFT monitor, under Geometry, you can set the size and also select the type of the monitor (i.e. point, line, 2D, or 3D):
I hope that I understood your question. If you are new into the software, I strongly recommend you to start with our getting started examples which will provide you step by step instructions on how to set your simulations, and also watch our webinars especially the introductory ones.
Thank you for your help.
