Refractive Index - an overview | ScienceDirect Topics

For X-ray photons, the real part of the refractive index of materials is smaller than the refractive index of air (n air ≅ 1) or vacuum (n vacuum = 1).Therefore, by impinging on a flat surface with α i < α c, the X-ray beam coming from air (or vacuum) undergoes total external reflection, that is, the beam is almost entirely reflected and there is no significant fraction of photons

The ordinary refractive index of 6H SiC has been measured from 2.43 μ (0.51 eV) to 0.336 μ (3.69 eV), using the transmission interference fringes of thin plates. Thibault’s data in the visible were used to normalize the dispersion curve. The index goes from 2.530 at 0.51 eV to 2.868 at 3.69 eV. The residual-ray and interband contributions to the index are evaluated. The extrapolated
