Fig. 6From: Fabrication of perfect plasmonic absorbers for blue and near-ultraviolet lights using double-layer wire-grid structuresAngular spectra of the angle-of-incidence dependence of the transmittance, reflectance, and absorptance (λ = 375 nm, p = 350 nm, duty ratio w/p = 0.52). a Simulation and b experimental. The arrow indicates the peak angle of the absorptance (dip angle of the reflectance)Back to article page
