3D maps of the dip minimum ((a) and (b)) and of the angular position ((c) and (d)) of the BSW when the higher (ZnS) and the lower (CaF2) refractive indexes layer thicknesses are spanned in a range of \(\text{300 nm}\) and \(\text{400 nm}\), respectively. The simulations are carried out for \(\lambda=5\:\mu\text{m}\). The simulations are carried out for both the \(\sigma\) ((a) and (c)) and the \(\pi\) ((b) and (d)) polarizations.
