In this work, we first introduce hyperuniform disordered patterns to a metal-insulator-metal gap plasmon metasurface and demonstrate enhanced wideband light absorption in the visible and near-infrared spectral region. Measurement of optical reflectance from fabricated periodic, hyperuniform disorder...
