Polarization-selective Nanogold Absorber by Twisted Stacking
Nano research（2023）
Abstract
Metamaterial absorbers show great promise for applications in optical manipulation, photodetection, solar energy harvesting, and photocatalysis. 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
