论文摘要
磁化等离子体中电磁波的非旋转转运是一个强大的构件，可用于理解和利用更通用的拓扑系统的性质。最近对这种介质中波浪相互作用的理论问题引起了很多关注，但是缺乏实验验证，即这种系统在实验室或工业环境中可能是可行的。这项工作通过证明单位分量（微波等离子体循环器）中的非记录性来提供实验概念概念。我们使用标准的波导规范设计了在4至6 GHz范围内运行的E-Plane Y连接等离子体循环器。从模拟和实验中，我们都可以观察到通过循环器传输的宽带隔离。可以通过更改等离子体密度和磁场强度来轻松调节循环器的性能和频带。通过链接模拟和实验结果，我们估计了该设备的血浆密度。
Nonreciprocal transport of electromagnetic waves within magnetized plasma is a powerful building block towards understanding and exploiting the properties of more general topological systems. Much recent attention has been paid to the theoretical issues of wave interaction within such a medium, but there is a lack of experimental verification that such systems can be viable in a lab or industrial setting. This work provides an experimental proof-of-concept by demonstrating nonreciprocity in a unit component, a microwave plasma circulator. We design an E-plane Y junction plasma circulator operating in the range of 4 to 6 GHz using standardized waveguide specifications. From both simulations and experiments, we observe wide band isolation for the power transmission through the circulator. The performance and the frequency band of the circulator can be easily tuned by changing the plasma density and the magnetic field strength. By linking simulations and experimental results, we estimate the plasma density for the device.
