摘要

旋转器对于高频微波系统的设计和优化是必不可少的。在这项研究中，我们实验展示了一种集成手性和回旋磁效应的被动超表面旋转器，以实现自由空间波传播中的非互易相移。该器件在8.55至9.15 GHz的频率范围内向前和向后传输之间保持大约π的相位差。它也有效地在斜入射横向磁（TM）和横向电（TE）极化。这种紧凑的无源超表面旋转器在波束转向和无线通信方面提供了有前途的应用。

Passive metasurface gyrators combining chiral and gyromagnetic effects

Gyrators are essential for designing and optimizing high-frequency microwave systems. In this study, we experimentally demonstrate a passive metasurface gyrator that integrates chiral and gyromagnetic effects to achieve nonreciprocal phase shifting in free-space wave propagation. The device maintains a phase difference of approximately π between forward and backward transmissions over a frequency range from 8.55 to 9.15 GHz. It also operates effectively at oblique incidences for both transverse magnetic (TM) and transverse electric (TE) polarizations. This compact, passive metasurface gyrator offers promising applications in beam steering and wireless telecommunications.

期刊介绍： Applied Physics Letters (APL) features concise, up-to-date reports on significant new findings in applied physics. Emphasizing rapid dissemination of key data and new physical insights, APL offers prompt publication of new experimental and theoretical papers reporting applications of physics phenomena to all branches of science, engineering, and modern technology. In addition to regular articles, the journal also publishes invited Fast Track, Perspectives, and in-depth Editorials which report on cutting-edge areas in applied physics. APL Perspectives are forward-looking invited letters which highlight recent developments or discoveries. Emphasis is placed on very recent developments, potentially disruptive technologies, open questions and possible solutions. They also include a mini-roadmap detailing where the community should direct efforts in order for the phenomena to be viable for application and the challenges associated with meeting that performance threshold. Perspectives are characterized by personal viewpoints and opinions of recognized experts in the field. Fast Track articles are invited original research articles that report results that are particularly novel and important or provide a significant advancement in an emerging field. Because of the urgency and scientific importance of the work, the peer review process is accelerated. If, during the review process, it becomes apparent that the paper does not meet the Fast Track criterion, it is returned to a normal track.
