In this paper, we propose a new mechanism for obtaining optical super-resolution based on anisotropic near-zero index metamaterials (AZIMs). It is found that AZIMs can not only achieve perfect transmission of electromagnetic energy but also realize a super-resolution lens. Moreover, we find the performance of super-resolution imaging is not sensitive to the loss and impedance mismatching, as analytically and numerically demonstrated. Our findings provide a new way to explore high-resolution optical imaging.

通过各向异性近零折射率超材料实现光学超分辨率的新机制

在本文中，我们提出了一种基于各向异性近零折射率超材料（AZIM）获得光学超分辨率的新机制。研究发现，AZIM不仅可以实现电磁能量的完美传输，还可以实现超分辨率镜头。此外，我们发现超分辨率成像的性能对损耗和阻抗不匹配不敏感，如分析和数值所示。我们的发现提供了一种探索高分辨率光学成像的新方法。
