S-parameters describe the frequency-dependent responses for all input and output port combinations and polarizations. In this video lesson, you will learn how to use the S-parameter primitive elements available in the Element Library.
The following video demonstrates how to set up and load data into an Optical N Port S-Parameter element from a component-level simulation of a Y-branch in FDTD.
The S-parameter data file loaded in this demonstration can be downloaded here.
The project file created at the end of the video can be downloaded here.
The phase of long waveguides changes quickly as a function of frequency due to the group delay. In this video lesson, you will learn about an alternative method for formatting the S-parameter file data to isolate it and make it work for long devices.
