Abstract

The review explores topologically trivial and nontrivial properties in electromagnetic metamaterials, focusing on their design principles and applications. Electromagnetic metamaterials, known for their ability to manipulate electromagnetic waves through artificial structures, have significantly advanced due to topological concepts. Topologically trivial metamaterials rely on traditional unit structures like resonators, employing geometric patterns to achieve desired wave control, such as absorption and polarization. In contrast, topologically nontrivial metamaterials utilize periodic arrangement and unique unit cells, leading to robust edge states and waveguiding properties protected against defects. Recent developments, including Möbius strip-inspired designs, demonstrate how these topological effects enhance electromagnetic functionality. The review emphasizes that the fusion of topology with metamaterials opens avenues for advanced applications in optics, communications, and quantum computing unlock new functionalities in various technological fields.

电磁超材料的拓扑平凡与非平凡性质

本文探讨了电磁超材料的拓扑平凡和非平凡性质，重点介绍了它们的设计原理和应用。电磁超材料以其通过人工结构操纵电磁波的能力而闻名，由于拓扑学概念而取得了重大进展。拓扑平凡的超材料依赖于传统的单元结构，如谐振器，采用几何图案来实现所需的波控制，如吸收和极化。相比之下，拓扑非平凡的超材料利用周期性排列和独特的单元胞，导致鲁棒的边缘状态和波导特性，防止缺陷。最近的发展，包括Möbius条形设计，展示了这些拓扑效应如何增强电磁功能。该综述强调，拓扑与超材料的融合为光学、通信和量子计算的先进应用开辟了道路，并在各个技术领域解锁了新功能。

期刊介绍： Reviews in Physics is a gold open access Journal, publishing review papers on topics in all areas of (applied) physics. The journal provides a platform for researchers who wish to summarize a field of physics research and share this work as widely as possible. The published papers provide an overview of the main developments on a particular topic, with an emphasis on recent developments, and sketch an outlook on future developments. The journal focuses on short review papers (max 15 pages) and these are freely available after publication. All submitted manuscripts are fully peer-reviewed and after acceptance a publication fee is charged to cover all editorial, production, and archiving costs.
