Polarization Insensitive Broadband Zero Indexed Nano-Meta Absorber for Optical Region Applications

Broadband response metamaterial absorber (MMA) remains a challenge among researchers. A nanostructured new zero-indexed (ZIM) is presented in this study, constructed with hexagonal shape resonator for optical region applications. The design consists of and dielectric layers made tungsten quartz (Fused). proposed absorbent exhibits average absorption more than 0.8972 (89.72%) within the visible wavelength 450–600 nm nearly perfect 0.99 (99%) at 461.61 nm. Based on computational analysis, can be characterized as ZIM. developments ZIM absorbers have demonstrated plasmonic resonance characteristics impedance match. incidence obliquity typically range 0°–90° both TE TM mode maximum absorbance (∼89.72%), up to 45° angular stability suitable solar cell applications, like exploiting energy. structure prototype designed simulated by studying microwave technology numerical computer simulation (CST) tools. finite integration technique (FIT) based simulator CST element method (FEM) HFSS also helps validate data absorber.
