A planar plasmonic metasurface composed of asymmetric gold nanostructures is shown to exhibit both anisotropic and chiral/pseudo‐chiral optical responses. By tailoring the polarization and angle of incidence, the metasurface significantly enhances optical chirality and enables enantiospecific detection.

This article proposes a symmetry‐protected bound states in the continuum mechanism based on borophene metamaterials, achieving dual‐band broadband coherent perfect absorption (CPA) in the near‐infrared spectrum. By dynamically modulating carrier concentration, the operational bandwidth of CPA can be significantly expanded, effectively overcoming the ...

This work presents an ultrathin terahertz metamaterial absorber that achieves broadband and polarization‐insensitive performance through multimode spoof‐plasmon resonances and tunable indium tin oxide loss engineering. The absorber offers near‐Rozanov‐limit thickness and optical transparency, enabling integration into compact and multifunctional THz ...
