Interference 2D centered square lattice

Scattering from cylinders positioned in a squared centered lattice.

  • The particles are cylinders with radii and heights of $3$ nm.
  • Their spatial distribution is composed of two square lattices (lattice length $l$), shifted by half a lattice length in both directions:
  • The first square lattice is centered at the origin, with a lattice length of $25$ nm.
  • The second one, with the same lattice spacing and the same type of particles at its nodes is initialized at $x = y = l/2 = 12.5$ nm.
  • The lattices’ base vectors are parallel to the axes of the reference cartesian frame.
  • The wavelength is equal to 0.1 nm.
  • The incident angles are $\alpha_i = 0.2 ^{\circ}$ and $\varphi_i = 0^{\circ}$.
