I am simulating a (using the FDTD module) multilayer for getting the electric field and SPR reflectance. I started using the tutorial provided in https://support.lumerical.com/hc/en-us/articles/360042160673-Surface-plasmon-resonance-in-a-glass-silver-air-slab.

Of course I have updated the geometry and the script, but at the end of the simulation, it seems that only a small portion of my geometry is simulated.

I would appreciate a support for this problem.

Hi, Without your file screen shots about some setting parameters, it is hard to tell. But, I guess if the script works without problem, the result seems ok, except for some parameter errors.
To confirm, you can do one or two simulations manually and see if there is E fields at large x, with normal incidence and one angle, say 44deg.
You can also use stackrt and stackfield to analytically get the results:
stackrt - Script command
stackfield - Script command
