  Hyperuniform geometries feature correlated disordered topologies which follow
from a tailored k-space design. Here we study gold plasmonic hyperuniform
metasurfaces and we report evidence of the effectiveness of k-space engineering
on both light scattering and light emission experiments. The metasurfaces
possess interesting directional emission properties which are revealed by
momentum spectroscopy as diffraction and fluorescence emission rings at
size-specific k-vectors. The opening of these rotational-symmetric patterns
scales with the hyperuniform correlation length parameter as predicted via the
spectral function method.
