简易对称三孔缝Babinet超表面中的Fano共振
Fano resonance in facile symmetric trimeric Babinet metasurface
摘要
Abstract
A facile symmetric trimeric Babinet metasurface is proposed for producing a Fano resonance in terahertz region.The Fano resonance is excited by an incident wave that interferes with the out-of-phase dark mode when a linearly polarized wave perpendicular to the Babinet slits illuminates the metasurface.By adjusting the structural parameters of the metasurface,the in-phase bright mode can be tuned independently,while the out-of-phase dark mode can be changed linearly,and the quality factor can also be tuned.Overall,a method for tuning the dark and bright modes for Fano resonance is revealed.The tuning mechanism has promise for applications in various fields such as sensors,filters,optical switches,photodetectors,and energy-harvesting devices with advanced performance.关键词
