摘要

本文研究了一种具有欺骗表面等离子激元(SSPPs)的新型环行器。在这封信中，考虑了sspp和内导体y结的组合。在不同波段，SSPPs传输模式和TEM模式占主导地位。这使得环行器具有宽带特性。在HFSS中对结构进行了优化，以获得更好的性能。在4.5 GHz ~ 13.5 GHz范围内，观测到较强的环流效应，证明该系统巧妙地实现了非互易传输特性。该环行器具有良好的非互反传输特性。此外，使用约束电磁波可以减小铁氧体的尺寸并显示出宽带特性。

Research of a circulator based on spoof surface plasmon polaritons

This paper shows a study of a new kind of circulator with spoof surface plasmon polaritons (SSPPs). In this letter, the combination of SSPPs and Y-junction in inner conductor is in consideration. SSPPs transmission mode and TEM mode is dominant in different band. That makes the broadband characteristic of the circulator. The structure is optimized in HFSS for better performance. From 4.5 GHz to 13.5 GHz, a strong circulation effect is observed and this proves that the nonreciprocal transmission characteristics are achieved skillfully. The circulator shows good nonreciprocal transmission characteristics. Moreover, the use of confinement electromagnetic waves can decrease the size of the ferrite and show a broadband characteristic.
