Plasmonic metasurface with quadrilateral truncated cones for visible perfect absorber

Solar radiation is mainly concentrated in the visible and infrared spectra ranges, its perfect absorption has great significance to solar cell, energy harvester, emitter, stealth, hot-electron device fields. In this study, we theoretically design numerically demonstrate a highly efficient broadband absorber (VPA) using plasmonic metasurface , which consists of quadrilateral truncated cones configuration. The electromagnetic properties VPA are discussed by changing geometrical parameters, especially intensity VPA. processes (100%) at wavelength 490 nm minimum 99.51% 772 nm. averaged 99.91% spanned whole spectrum. excellent performance revealed Fabry-Perot resonance, localized surface plasmon resonance (SPR), propagating SPR . exhibits ultrahigh absorption, wide incident angle, polarization-independent characteristics. It proves that designed potential thermal photovoltaics harvesting applications. • A presented. average intensities 99.91%, 99.8%, 94.7% angles 0°, 20°, 60°, respectively.
