Measured absorption spectra for the narrow-band and broadband absorbers (left column), and scanning-electron microscopy (SEM) images on the right show unit cells of the fabricated structure for each case (scale bars represent 100 nm).

Plasmonic absorber in (a) and (b) consists of the Ag/SiO2/Ag (100/34/100 nm), while absorber in (c) and (d) consists of Ag/Al2O3/Ag (100/34/100 nm). (e) and (f) show broader absorption spectrum with absorber consisting of Au/SiO2/Au (100/60/100 nm).
