Light‐Controlled Fabrication of Disordered Hyperuniform Metasurfaces

Abstract Disordered hyperuniformity (DHU) is one of the most prominent manifestations engineered disorder, which aims to circumvent limitations commonly related order. Considering k ‐space, isotropic DHU characterized by an suppression scattering for wavenumbers approaching zero. Thereby, stealthy a particularly strong form DHU, where even suppressed 0 < ≤ K within circular window radius . Although experimental demonstrations in optical structures exist, scalable and low‐cost fabrication methods are still rare often lack opportunity in‐situ control ‐space. Here, novel facile bottom‐up approach metasurfaces presented. Starting with solution‐based deposition procedure silver nanoparticles (AgNPs) darkness (resulting DHU), more extensive way ‐space engineering introduced illuminating growing metasurface light DHU). While it shown that wavelength incident allows , its lateral momentum ∥ defines additional design parameter. The light‐controlled growth under maximum via surface plasmon polaritons enables confirmation theoretically predicted phenomenon anisotropic DHU.
