Figure 4
Variation along the WG of the intensity integrated over the channel width, normalized to the incident integrated intensity, for different incident angles θin, in (a) the structured WG, (b) the uniform WG. In both cases the vacuum gap was deff = 241 nm and the incident energy was 8 keV. The period P in the structured WG was 200 µm. The figure clearly shows selective transmission for the structured WG. |
