Hyperuniform geometries feature correlated disordered topologies which follow
from a tailored k-space design. Here, we study gold plasmonic hyperuniform
disordered surfaces and, by momentum spectroscopy, we report evidence of kspace
engineering 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.
