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 disordered, and random pattern gap plasmon metasurface devices has revealed the origins of the two resonance modes of the gap plasmon metasurface structure: a localized gap plasmon resonance mode and a non-local guided optical resonance mode. The technique of using hyperuniform disordered patterns for investigating complex resonance modes of structured materials can be used for design of a variety of new metamaterials.

近完美光吸收体的超均匀无序金属-绝缘体-金属间隙等离子体超表面

在这项工作中，我们首先将超均匀无序图案引入金属-绝缘体-金属间隙等离子超表面，并在可见光和近红外光谱区域展示了增强的宽带光吸收。对制造的周期性、超均匀无序和随机图案间隙等离子体超表面装置的光学反射率的测量揭示了间隙等离子体超表面结构的两种共振模式的起源：局部间隙等离子体共振模式和非局部引导光学共振模式。使用超均匀无序模式研究结构材料的复杂共振模式的技术可用于设计各种新的超材料。
