Hi
I am working on srr metamaterial absorbers. I want to vary the angle of incidence of the plane wave which is now normal by default. Can anyone help me with how to do it?

Hi MEGHA_UNNI,

In the future, such questions may be more appropriately asked in the Electromagnetic Design and Simulation forum, as this one is more oriented towards theory.

On to your question:

Since you're working with a metamaterial absorber, I assume you are simulating just a single unit cell. In this case, you would want to use a Floquet port as an excitation. Floquet ports are used often to scan the angle of incidence in periodic arrays - there is a great tutorial on how to use them included with HFSS. Let us know if you have any problems with it.

Good Luck!
