I have calculated S- parameters in FDTD and imported it to interconnect. I used two methods to compare my results. Firstly, I calculated s-parameters for each of the layers and extracted it to interconnect. For the second method, I extracted s-parameters for the whole structure once and exported it to interconnect. However, the results of transmission plots are not the same.

Is there away I can visualize reflectance for my design as well in interconnect?

Attached are screenshots of the two results:

Hi Odebowale
To visualize the reflection, you may setup ONA with 2 input ports, then connect the second input port to "port 1" of your s-parameter. In this case when you excite light to "port 1" of the s-parameter element, the reflection to this port itself can be measured.

Thanks so much. This answer my first question
Please do you have idea on how I can combine two or more s-parameters elements? I fill like the way it is connected above is not correct because there should be "multiplier" to combine each of s-parameter elements. Any idea will be much appreciated
