简介
Novel design of flexible chiral metasurface has been attractive to control electromagnetic dynamics for fabricating integrated enantiomeric sensing devices. In this article, a reconfigurable metasurface decorated with planar magnetoplasmonic microbundle arrays of Au@Fe3O4 core‐shell nanowires (NWs) on polydimethylsiloxane film is fabricated. Its chiroptical property is willingly manipulated by skew angle (θ), that is, the angle between applied magnetic field vector (B) and tangent vector (T) of a curved metasurface. Interestingly, the as‐prepared NW metasurface presents many internal skew angles (θin) among respective NWs at nanoscale as well as additional external skew angle (θex) among arrays at microscale, extraordinarily enhancing chiroptical signal compared to other nanosphere or single NW arrays where lack of θin is observed. Computational simulation proves the disruption of the symmetry via …
