N2 - Hyperuniform geometries feature correlated disordered topologies which follow from a tailored k-space design. Here, we study gold plasmonic hyperuniform disordered (HuD) surfaces and, by momentum spectroscopy, we report evidence of k-space engi- neering on both light scattering and light emission. Even if the structures lack a well- defined periodicity, emission and scattering are directional in ring-shaped patterns. The opening of these rotational-symmetric patterns scales with the hyperuniform correlation length parameter as predicted via the spectral function method.
