Size-distribution model: decoupling approximation

Scattering from a distribution of cylinders of two different sizes using the Decoupling Approximation.

  • The sample is made of cylinders deposited on a substrate.
  • The distribution of particles is made of:
    • 80% of cylinders with radii and heights equal to $5$ nm
    • 20% of cylinders with radii and heights equal to $8$ nm.
  • The interference function is Radial Paracrystal with a peak distance of $18$ nm and a damping length of $1$ $\mu$m.
  • The wavelength is equal to 0.1 nm.
  • The incident angles are $\alpha_i = 0.2 ^{\circ}$ and $\varphi_i = 0^{\circ}$.
