Metamaterial Modeling

Dear Sir,
I have made a model. It has silicon substrate and gold “U” structure array. I am expecting it to give metamaterial effect like negative effective refractive index or reflection in reverse direction.

What I have to do, which monitors I have to place at which position. Moreover, on running simulation it is showing diversion problem. Please help me out for this.

Here is the information that can help you:

To be more specific, could you provide your simulation file? This way the audience of the forum will help you more likely )
