“…Recently, many efforts have been recently focused on the extension of absorption band and control of absorption frequency range in visible light regime for practical applications like photovoltaic device, photodetector, thermal emitter, and pulse generation [9]- [19]. To obtain broadband absorption, several approaches have been developed such as using a multi-shaped/sized architecture on planar structure and staking of metal/dielectric layers.…”

We report a numerical study of a broadband metamaterial absorber in visible light region by utilizing a single layer of metal-dielectric-metal configuration. The absorption bandwidth and absorption performances are tailored by varying the resonator shapes and metal materials. The absorption bandwidth of the proposed metamaterial absorber (MA) structure is enhanced significantly with decreasing the order of rotational symmetry of the resonator shape. Using gold configuration, the twofold symmetry MA structure based on the double-sized axe shaped resonator exhibits the broadband absorption response over the entire visible light and apart of infrared spectrum range from 320 to 982 nm with absorptivity above 90% for both transverse electric and transverse magnetic polarizations. The physical mechanism of broadband absorption is explained by the current, electric, and magnetic distributions, significantly affected by the propagating surface and localized surface plasmon resonances. Furthermore, the high absorber performances of the twofold symmetry MA structure can be obtained over entire visible light region (400-700 nm) for both noble metal of gold and low-cost metal of nickel configurations, indicating the proposed absorber is a promising candidate for low-cost and large-scale fabricate device operated in visible light region.

“…A metasurface resonator base absorber with three crossed layers of gold-dielectric glass is above 70% from 400-1000 nm [23]. An ultra-wideband matrix-shaped MMA is exhibited 80% absorbance between 474.4 nm-784.4 nm [24]. A thin film resonator having with aluminium (Al) and indium tin oxide (ITO) has a more significant specific absorption of 90% for large transmission capacity utilizing 100 nm P3HT, PCBM and P3HT: PCBM heterostructure [25].…”

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.

Broadband response metamaterial absorber (MMA) remains a challenge among researchers. A nanostructured new Zero Indexed Metamaterial (ZIM) absorber is presented in this study, which is constructed with a hexagonal shape resonator for the optical region applications. The design consists of a resonator and dielectric layers made with tungsten and quartz (Fused), respectively. The proposed absorbent exhibits average absorption of more than 0.8972 (89.72%) within the visible wavelength of 450-600 nm and almost perfect absorption 0.99 (99%) at 458.54 nm. Based on computational analysis, the proposed absorber can be characterized as Zero Indexed Metamaterial. 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 35° angular stability, which is suitable for solar cell applications, like exploiting solar energy. The proposed structure prototype is designed and simulated by a study of microwave technology numerical computer simulation (CST) tools. Finite integration technique (FIT) and finite element method (FEM) is performed to data analysis in CST software, and HFSS also helps validate the numerical data of the proposed ZIM absorber. The proposed MMA design is appropriate for substantial amounts of absorption, wide-angle stability, absolute invisible layers, magnetic resonance imaging (MRI), color images, and thermal imaging applications.
