Hello I have checked a lots of simulations with many varying conditions, with various nanoantenna geometry, and different metals.
The YZ monitor is placed exactly at the Block boundary (block bc in x and y direction and pml in z direction).
As I mentioned earlier depending on the geometry of the nanoantenna sometime the YZ monitor efficiency of transmission shows zero sometime not zero at all. Even if I put the YZ monitor inside the boundary there are values of transmission efficiency.
If there is an inconsistency with physics of the simulation result then how can we rely on the Lumerical result?
Could you please help me with a simulation set up for slab mode Using FDE where say there is some nanoantenna over a dielectric, over the metal layer?
Thank you
