Hyperuniform geometries feature correlated disordered topologies which follow from atailored k-space design. Here, we study gold plasmonic hyperuniform disordered surfaces and, by momentumspectroscopy, we report evidence of k-space engineering on both light scattering and lightemission. Even if the structures lack a well-defined periodicity, emission andscattering are directional in ring-shaped patterns. The opening ofthese rotational-symmetric patterns scales with the hyperuniform correlation lengthparameter as predicted via the spectral function method
