Hi everybody,
I would like to know if someone could explain to me what happens to the refraction index of gold at grazing angle (X-ray applications), and particularly the band structure explanation (if you have it!)...
Indeed, I heard that the x-ray telescopes were made of parallel mirrors for the material to absorb the rays at grazing angle, the only way for them to REFLECT these high-energy rays.
Thank you very much,
