近日，华南师范大学韦中超团队研究了使用超分子Pancharatnam-Berry相的手性超表面。相关论文于2025年9月8日发表在《物理评论A》杂志上。

Pancharatnam-Berry （PB）相具有应用方法简单、理论框架全面的特点，在设计全息图和纳米印刷的超表面方面具有显著的优势。然而，PB相在很大程度上依赖于分析仪来实现纳米打印。此外，利用PB相设计手性元表面存在很大的挑战，限制了其在多功能元表面中的应用。

研究组介绍了一种基于超分子的超分子Pancharatnam-Berry相，使手性超表面的设计成为可能。元分子可以独立和任意地调整强度和相位，而不需要分析仪。通过将手性因子引入到超分子中，所提出的手性超表面实现了偏振敏感的纳米打印和全息图，而不需要使用分析仪。该方法解决了传统PB相位在近场调制和手性研究中的局限性，同时为智能超表面的小型化和先进性提供了理论基础。

Abstract: The Pancharatnam-Berry (PB) phase is characterized by the simple application method and comprehensive theoretical framework, offering significant advantages in designing metasurfaces for hologram and nanoprinting. However, the PB phase relies heavily on an analyzer to enable nanoprinting. Additionally, designing a chiral metasurface by the PB phase poses significant challenges, limiting the application in multifunctional metasurfaces. This paper introduces a metamolecular Pancharatnam-Berry phase based on metamolecules to enable the design of chiral metasurfaces. Metamolecules can independently and arbitrarily adjust intensity and phase without the need for an analyzer. By introducing the chiral factor to metamolecules, the proposed chiral metasurface achieves polarization-sensitive nanoprinting and hologram without the use of an analyzer. This approach addresses the limitations of the traditional PB phase in near-field modulation and chiral research while providing a theoretical foundation for the miniaturization and advancement of intelligent metasurfaces.
