Spatial correlations boost absorption efficiency.

Enhanced absorption is broadband and angularly robust.

Potential for designing low-density blackbody-like absorbers.

Abstract

We study the propagation of waves in a set of absorbing subwavelength scatterers positioned on a stealth hyperuniform point pattern. We show that spatial correlations in the disorder substantially enhance absorption compared to a fully disordered structure with the same density of scatterers. The non-resonant nature of the mechanism provides broad angular and spectral robustness. These results demonstrate the possibility to design low-density materials with blackbody-like absorption.
