Fano resonance in asymmetric plasmonic nanostructure: Separation of Sub-10 nm Enantiomers

Separating enantiomers is vital in chemical syntheses, life sciences, and physics. However, the usual chemical processes are inefficient. Recently, plasmonic nanostructures have drawn considerable attention for manipulating nanoparticles; however, …

Tunable Mid‐Infrared Phase‐Change Metasurface

The intense light–matter interaction of plasmonic metasurfaces provides an appealing platform for optical sensing. To date, most metasurface sensors are not spectrally tuned. Moreover, they operate in a total reflection mode, which complicates the …
