摘要

This work demonstrates tailored hemispherical absorptance A, reflectance R, and transmittance T spectra at the coexistence of three resonances. The localized surface plasmon resonance (LSPR) is excited by a hexagonal array of 15-nm-thick circular Au pillars at the wavelength λLSPR. The Berreman and epsilon near zero (ENZ) mode resonances are generated within a fixed region λENZ ≈ 1.5 μm using diffracted waves inside a 230-nm-thick indium-tin-oxide film. The λLSPR of four samples approaches λENZ via increasing pillar diameters. For the first time, a broadband absorptance enhancement resulting from three compatible resonances is shown. The resonance compilation together with material loss cause failure of a popular LSPR indicator, which are replaced by the robust indicators proposed here.
