Terahertz reconfigurable Fano-resonant plasmon induced transparency in liquid crystal meta-switches
This study presents an electrically-controlled hybrid plasmon-induced transparency (PIT) metadevice leveraging on nematic liquid crystals for enabling active manipulation of terahertz slow light. Achieving Fano-resonant response via near-field coupling of chiral and achiral meta-atoms facilitates nonlinear terahertz generation and mitigates radiative losses. These findings highlight the potential of Fano-resonant active metasurfaces for advanced sensing and slow-light devices.
