In the proposed tungsten based absorber for visible regime, the structure contains a ground plane made up of a metal underneath a dielectric layer which in turn is below a resonating structure made up of a same metal as ground plane (metal-dielectric-metal) as shown in Fig. 1. The dielectric layer is made up of silicon dioxide (SiO 2).
The proposed multilayered Tungsten-MgF₂-SiO₂-MXene-Au solar absorber configuration achieves unprecedented absorption efficiency of 99.99% across the 100–1600 THz frequency domain, maintaining superior performance at 60° incidence angles .
In this paper, novel absorbers using tungsten-metasurface are developed which give ultrahigh absorbance over a wide frequency spectrum. The proposed designs are two-dimensional, polarization insensitive, broadband and are predicted to give better response under high temperatures ascribed to high melting point of tungsten i.e. 3422 °C.
Major motivation behind the research is introduction of tungsten (W) for nanostructure layer which has higher melting point than any other metal i.e. Gold (Au), Silver (Ag), Chromium (Cr), Copper (Cu) and even Titanium Nitride (TiN) which is a refractory material.
