Dear Chinmay,

Thank you for the response. Yes, I have created the frequency sweep in the solution setup.

I also used Results>Create Modal Solution>Rectangular Plot and clicked on the S11 parameter.

The problem is that it displays the same graph for S11 even if I change the material of the silicon wafer to galium arsenide or anything else. I think the S11 parameter is shown for the excitation that I showed in my post(at the back face of the radiating element).

I need the S11 or anything else that can give me information about the reflected wave at the face of the wafer in order to see how different materials react to the electromagnetic field of the radiation element. 

Right now S11 gives me information only about the S11 at the excitation of the radiating element.

Regards,

Kristiyan
