Hello Gun, Thank you for quick response.
Well this is a plasmonic structure and I am using Block BC. And obviously for a lot of simulations based on what type of structure I have as for nanoantenna the Side monitor are not giving zero intensity.
My main goal is to understand and calculate how much power and efficiency is going to the side way towards the dielectric layer.
Is there any way Lumerical package can do that please?
Thank you
