Figure 6
The intensity distribution of the focused beam on the focal plane in a RDL with a silicon lens. Shown are the cases corresponding to = 0 (a), = 1.5 × 10-4 (b), = −1.9 × 10-4 (c). The beam falls at the Bragg-corrected angle corresponding to = 0. Absorption in the lens is taken into account. Computer calculation performed using formula (65). Incident plane wave. |
