Abstract: Abstract In this paper, we design and numerically investigate an ultrathin polarization-insensitive, broadband visible absorber based rectangular metagratings. The absorber, consisting of a dielectric grating grown in a metallic substrate with a vertically metallic covering,… read more here.

DOI: 10.3390/nano11102709
Abstract: A polarization-insensitive broadband terahertz absorber based on single-layer graphene metasurface has been designed and simulated, in which the graphene metasurface is composed of isolated circular patches. After simulation and optimization, the absorption bandwidth of this… read more here.
