WebDec 20, 2024 · Since the polarizers are based on x-ray diffraction by crystals, all matrix elements depend on the incident angle and the wavelength λ. In particular, the components pππ and aππ depend strongly on the Bragg angle since any deviation from 45° leads to a strong increase in these matrix components. FIG. 1.
