An optical metamaterial is capable of manipulating light in nanometer scale that goes beyond what is possible with conventional materials. Taking advantage of this special property, metamaterial-assisted illumination nanoscopy (MAIN) possesses tremendous potential to extend the resolution far beyond conventional structured illumination microscopy. Among the available MAIN designs, hyperstructured illumination that utilizes strong dispersion of a hyperbolic metamaterial (HMM) is one of the most promising and practical approaches, but it is only theoretically studied. In this paper, we experimentally demonstrate the concept of hyperstructured illumination. A ∼80 nm resolution has been achieved in a well-known Ag/SiO₂ multilayer HMM system by using a low numerical aperture objective (NA = 0.5), representing a 6-fold resolution enhancement of the diffraction limit. The resolution can be significantly improved by further material optimization.

双曲线超材料辅助照明纳米显微镜的实验演示

光学超材料能够处理纳米级的光，这超出了传统材料所能达到的范围。利用这种特殊的特性，超材料辅助照明纳米显微镜（MAIN）具有巨大的潜力，可以将分辨率扩展到远远超过传统的结构照明显微镜。在可用的MAIN设计中，利用双曲线超材料（HMM）的强分散性的超结构照明是最有前途和实用的方法之一，但仅在理论上进行研究。在本文中，我们通过实验证明了超结构照明的概念。在众所周知的Ag / SiO _2中获得了约80 nm的分辨率多层HMM系统通过使用低数值孔径物镜（NA = 0.5），表示衍射极限的分辨率提高了6倍。通过进一步的材料优化，可以显着提高分辨率。
