Evolution of the angles, and distributions in two-dimensional arrays oscillators on a square (b,c) and hexagonal (e,f) lattices in 8 × 8 (b,e) and 7 × 9 (c,f) arrays for α = 0.7 (T = 296 K and Rf = 0.7 µm). The oscillators are indexed as indicated in the geometrical configurations of the array represented in (a,b). The oscillators show a cooperative behaviour by tending to have the same angle at a given time. The average orientation is along the axis of the long edge of the rectangular array: the angles distribution is centred on θ = 0 in (e), θ = π/2 in (c,f), and uniform in the square configuration in (b).
