超颖表面辅助纳米打印技术具有超小型化和亚波长分辨率的特点，作为一种图像显示光学器件得到了广泛的研究。它也为信息复用提供了一个平台，出现了一系列基于入射偏振、工作波长和观测角度的复用工作。然而，角度复用纳米打印的实现是以图像分辨率降低或制造难度增加为代价的，阻碍了其实际应用。在这里，受雅可比-安格展开的启发，提出了一种用于角度复用纳米打印的相位辅助设计范例，称为贝塞尔元表面。通过精心设计贝塞尔超颖表面的相位分布，可以将目标图像编码到期望的观察角度，达到角度复用。我们相信，我们的设计策略将是有吸引力的在现实世界中的应用，包括光学信息存储，加密/隐藏，多功能可切换光学器件，和3D立体显示等的优点，超紧凑和易于制造。
Featuring with ultracompactness and subwavelength resolution, metasurface-assisted nanoprinting has been widely researched as an optical device for image display. It also provides a platform for information multiplexing, and a series of multiplexed works based on incident polarizations, operating wavelengths and observation angles have emerged. However, the angular-multiplexing nanoprinting is realized at the cost of image resolution reduction or the increase of fabrication difficulty, hindering its practical applications. Here, inspired by the Jacobi-Anger expansion, a phase-assisted design paradigm, called Bessel metasurface, was proposed for angular multiplexing nanoprinting. By elaborately designing the phase distribution of the Bessel metasurface, the target images can be encoded into the desired observation angles, reaching angular multiplexing. With the merits of ultracompactness and easy fabrication, we believe that our design strategy would be attractive in the real-world applications, including optical information storage, encryption/concealment, multifunctional switchable optical devices, and 3D stereoscopic displays, etc.
