诸如循环器、隔离器和回转器的非互易组件在许多微波无线应用中找到实用性，包括高功率发射器、同时发射和接收通信和雷达系统以及新兴的低温量子计算实现。如今，这些元件使用铁氧体材料实现，铁氧体材料在外部磁场的作用下失去了它们的互易性。然而，铁氧体材料与半导体集成电路制造工艺不兼容，因此铁氧体非互易组件难以集成到芯片级，使得它们体积庞大且昂贵。在过去的50年里，这激发了对非磁性非互易元件的重大研究。近年来，时间调制非互易元件及其集成到硅集成电路中的突破，使这项研究得到了进一步的发展。本文回顾了非互易电子学的历史，综述了该领域的最新研究成果，并描述了未来研究的突出方向。
Non-reciprocal components such as circulators, isolators and gyrators find utility in numerous microwave wireless applications, including high-power transmitters, simultaneous transmit-and-receive communication and radar systems, and emerging cryogenic quantum computing implementations. Today, such components are implemented using ferrite materials, which lose their reciprocity under the application of an external magnetic field. However, ferrite materials are incompatible with semiconductor integrated-circuit fabrication processes, and therefore ferrite non-reciprocal components are difficult to miniaturize to chip scales, rendering them bulky and expensive. This has motivated significant research into non-magnetic non-reciprocal components over the past 50 years. In recent years, this research has been invigorated by breakthroughs in time-modulated non-reciprocal components, and their integration into silicon integrated circuits. This paper reviews the history of non-reciprocal electronics, surveys recent research results in the area, and describes outstanding directions for future research.
