Web13 de abr. de 2024 · In this work, we present a twisted stacked metamaterial design that serves as a plasmonic perfect absorber with polarization selectivity. Leveraging effective energy localization, the metamaterial realizes a near-unity absorbance of up to 99.6% for right circularly polarized incidence and 97.2% for left circularly polarized incidence.
