Hi! I'm trying to simulate for an active reflectarray unit-cell with 2 diodes. The diodes are modelled as lumped RLC components.

In order to realize the 4 modes of the 2 diodes using 1 design, I assigned parameters for the values R and C of each lumped component, and do the parametric sweep. It would be something like this

Mode 00 (R1=0ohm, C1=20fF, R2=0ohm, C2=20fF)

Mode 01 (R1=0ohm, C1=20fF, R2=2ohm, C2=0)

Mode 10...

Mode 11...

The results for the 4 modes when I did this were incorrect (they were all the same), which were different from when I simulated the 4 modes separately and copy paste the data into 1 plot. I'm trying to figure out what went wrong but I have no idea.

Thank you for your help!

Hi Praneeth,

Thank you for your reply! I was using Ansys Electronic Desktop 2022 R1.2

Did I tag the wrong product? If so, can you show me how to change that?

Hi Huy Nguyen,

Thanks for the reply. Your patience on this query is much appreciated.

Let me rephrase my question - please confirm if you are using HFSS or Maxwell design type of the Ansys Electronics Desktop to help us serve you better.

Best regards,
