Scattering from elongated particles positioned in a two-dimensional rectangular lattice.
Each particle has a sinusoidal profile (“Ripple1” form factor) with a length of $100$ nm, a width of $20$ nm and a height of $4$ nm.
They are placed along a rectangular lattice on top of a substrate.
This lattice is characterized by a lattice length of $200$ nm in the direction of the long axis of the particles and of $50$ nm in the perpendicular direction.
The lattice’s base vectors coincide with the reference Cartesian frame.
The wavelength is equal to 0.16 nm.
The incident angles are $\alpha_i = 0.3 ^{\circ}$ and $\varphi_i = 0^{\circ}$.
