超均匀几何的特征是相关的无序拓扑结构，这些拓扑结构来自定制的k空间设计。在这里，我们研究金等离子体超均匀无序表面，动量光谱，我们报告的证据kspace工程光散射和光发射。即使结构缺乏明确的周期性，发射和散射也是环形图案中的方向性的。这些旋转对称模式的开放尺度与超均匀相关长度参数通过谱函数方法预测。(C)2017年作者。所有文章内容，除非另有说明，是根据知识共享署名（CC BY）许可证许可。
Hyperuniform geometries feature correlated disordered topologies which follow from a tailored k-space design. Here, we study gold plasmonic hyperuniform disordered surfaces and, by momentum spectroscopy, we report evidence of kspace engineering on both light scattering and light emission. Even if the structures lack a well-defined periodicity, emission and scattering are directional in ring-shaped patterns. The opening of these rotational-symmetric patterns scales with the hyperuniform correlation length parameter as predicted via the spectral function method. (C) 2017 Author(s).
