A Highly Efficient Infinity-Shaped Large Angular- and Polarization-Independent Metamaterial Absorber

An efficient diagonally symmetric infinity-shaped broadband solar absorber has been demonstrated in this research paper. The structure was developed with an resonator made of titanium (Ti) and gallium arsenide (GaAs) at the base substrate layer to achieve absorption a wideband spectrum under energy radiation, efficiencies were calculated employing finite element method. average ranges from ultraviolet mid-infrared regions, 93.93% band is achieved. Moreover, bandwidths 2800 1110 nm observed, and, these bands, we attained continuous above 90% 95%, respectively, rates 96.25%, respectively. Furthermore, based on absorber, which optimized after varying many design parameters, it also observed that angle-insensitive 0° 50° polarization-insensitive results transverse electric (TE) magnetic (TM) modes. highly provides absorptance can be used as cells.
