摘要

电磁(EM)超材料是一个前沿领域,它通过人工设计和排列微观结构阵列来自由地操纵电磁场和波,从而实现异常宏观特性。微观结构阵列的单元胞也称为元原子,它可以构造传统材料中不存在或传统技术难以实现的有效介质参数。通过与数字信息的深度融合,元原子进化为数字元原子,导致信息超材料的出现。信息超材料打破了电磁和数字领域之间的固有障碍,为同时控制电磁波和调制数字信息提供了物理平台。元原子和超材料的概念也被引入到高频集成电路设计中,以解决传统方法无法解决的问题,因为集中参数模型在微观尺度上是不可持续的。通过将几个元原子结合形成一个元原子,可以在微观尺度上实现对电磁场分布的精确控制。在此基础上,我们总结了元原子的物理内涵和主要分类,并简要讨论了其未来的发展趋势。通过本文,我们希望引起更多的研究关注,探索元原子的潜在价值,从而为超材料的深入发展开辟更广阔的舞台。

Meta-atoms: From Metamaterials to Metachips.

Electromagnetic (EM) metamaterials represent a cutting-edge field that achieves anomalously macroscopic properties through artificial design and arrangement of microstructure arrays to freely manipulate EM fields and waves in desired ways. The unit cell of a microstructure array is also called a meta-atom, which can construct effective medium parameters that do not exist in traditional materials or are difficult to realize with traditional technologies. By deep integration with digital information, the meta-atom is evolved to a digital meta-atom, leading to the emergence of information metamaterials. Information metamaterials break the inherent barriers between the EM and digital domains, providing a physical platform for controlling EM waves and modulating digital information simultaneously. The concepts of meta-atoms and metamaterials are also introduced to high-frequency integrated circuit designs to address issues that cannot be solved by traditional methods, since lumped-parameter models become unsustainable at microscopic scales. By incorporating several meta-atoms to form a metachip, precise manipulation of the EM field distribution can be achieved at microscopic scales. In this perspective, we summarize the physical connotations and main classifications of meta-atoms and briefly discuss their future development trends. Through this article, we hope to draw more research attention to explore the potential values of meta-atoms, thereby opening up a broader stage for the in-depth development of metamaterials.
