The distance between structure interface and PML(boundary) should be least half maximum wavelength (800nm). This is due to because the evanescent field might affect the PML and therefore the observation. If the observation (Transmission/Reflection) position inside the evanescent field range, then might stored the return energy flux and lead to some oscillation spectrum.
Here: Z- and Z+ (Grids) = 100 → Z Length: Z-/+ (Grids) * dx = 500 nm + 500 nm (CAD space) >> 800nm/2
The incident wave is linear polarization in y axis (pis=90) from upper side(theta =180).
