Abstract

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