Nanoantenna - reflectance , transmittance monitor position

Dear all,

I simulated nano antenna ad found its extinction cross section using TFSF source. Now when I measure my sample with micro FTIR ,I can able to measure reflection and transmittance. Now I have confusion in placing Reflection and Transmittance monitors in my simulation setup. I kindly request you to suggest the position of monitor to be placed to calculate R and T for my structure.

I herewith attached my simulation setup for your kind reference.

Thank You!!!
