Asymmetric X-ray diffraction of confined beams in crystals

Asymmetric dynamic diffraction of confined X-ray beams in crystals has been theoretically studied using Takagi-Taupin equations, including numerical solution using nodal grid and calculations of X-ray fields in Fourier space. We have fulfilled simulation of scattering intensity distribution maps from silicon crystal near reciprocal lattice site depending on size of X-ray beams.
