论文摘要
在本文中，我们讨论了基于通过时空调制赋予的角动量偏见的合成形式的无磁性非重生结构的最新进展。我们讨论了这样的组件如何支持与传统磁性铁氧体设备相当的性能指标，同时由于消除磁性偏差而导致的尺寸，重量和成本降低，提供了明显的优势。我们进一步根据这些组件提供了潜在的应用程序和未来方向的前景，从无线全双工通信到元信息和拓扑绝缘子。
In this paper, we discuss recent progress in magnet-free non-reciprocal structures based on a synthetic form of angular momentum bias imparted via spatiotemporal modulation. We discuss how such components can support metrics of performance comparable with traditional magnetic-biased ferrite devices, while at the same time offering distinct advantages in terms of reduced size, weight, and cost due to the elimination of magnetic bias. We further provide an outlook on potential applications and future directions based on these components, ranging from wireless full-duplex communications to metasurfaces and topological insulators.
