Thank you Amrita for the reply.
Placing the monitor at the top and bottom is fine, I have done that for comparing forward and backward emissions. But I want to see the the radiation profile of the dipole placed inside the metasurface, and how it couples to the outside and the substrate. Radiation along XZ and YZ will tell about how symmetric the radiations are, which is needed for my case. Please find something if it is possible to calculate.
Even if I use this "Scat_ff" object how much error will it introduce in the result? Will it be totally wrong?
Even it has helped me to get some ideas for further analysis. So it would be great if I am able to show some radiation profiles in my article.
