“…Benefiting the absorption mechanism of the broadband absorber proposed in this paper can be summarized as the result of localized surface plasmon resonance, strong plasma near-field coupling, Fabry–Perot resonance and the unique properties of high-loss materials [ 19 , 24 , 25 , 27 , 28 ]. In order to better explain the internal mechanism causing wide spectrum absorption, this paper further studies the electric field intensity distribution diagram and the magnetic field intensity distribution diagram corresponding to three absorption peaks, as shown in Figure 3 , in which (a)–(f) are the electric field diagrams in X–Y plane and the X–Z plane, and (g)–(l) are the magnetic field diagrams in X–Y plane and the X–Z plane.…”

In recent years, research on solar absorbers provides a significant breakthrough to solve the energy crisis. A perfect solar absorber based on a four-corner star array is designed and the absorption performance is analyzed numerically. The results show that the absorber reaches more than 90% of the full band in the range of 400–2000 nm. In particular, the absorption efficiency of the continuous more than 95% of the bandwidth reached 1391 nm, and the average absorption efficiency of the whole study band is more than 98%, and the loss of the solar spectrum only accounted for 2.7%. At the same time, the absorption efficiency can be adjusted by changing the geometric structure of the absorber. In addition, due to the perfect symmetry of the structure, it has an excellent insensitivity of the incident angle and polarization angle. In general, the proposed solar absorber has exciting prospects in solar energy collection and utilization, photothermal conversion and other related fields.

The concept of achieving perfect absorption of electromagnetic (EM) waves has engendered substantial interest in diverse applications, encompassing photoelectric conversions, infrared imaging, energy harvesting, and photovoltaics. Conventionally, absorber materials of choice have revolved around the utilization of refractory metals. However, this article proposes a pioneering proposition that uses quasi-twodimensional (quasi-2D) material i.e., MXene and uses ceramics material aluminum nitride (AlN) to forge a polarization-insensitive broadband absorber. This ultra-broadband meta-absorber showcases an expanse of absorbance across a comprehensive spectral range, spanning from the ultraviolet (UV) to Near-infrared (NIR) regions, specifically extending from 200 nm to 2000 nm. To previse the angular stability of the meta-absorber, the absorptivity was examined under oblique incidence in both transverse electric (TE) and transverse magnetic (TM) polarizations exhibiting the robustness of broadband absorber. MXene shows exceptional mechanical flexibility, facilitating seamless integration into flexible electronics. Their large specific surface area holds significant promise for high-performance energy storage in applications including energy harvesting, photovoltaics, solar cells, and sensors. These unique characteristics position them at the forefront of material science, driving advancements in next-generation technologies.

“…Optical absorbers have attracted considerable research attention for their potential to be used in applications, including solar energy [1,2], sensing [3,4], thermal radiation [5,6], imaging [7], and optical switching [8]. With the development of electromagnetic simulation and micro-nano processing technology, scientists have proposed a variety of perfect optical absorbers that can perfectly absorb light waves based on various micro/nano-structures, such as metamaterials [3,9,10], metasurface [11][12][13], and photonic crystals [14][15][16]. Micro/nano-structures that can excite the interface mode have also been used in the development of perfect optical absorbers in recent years.…”

In this study, we theoretically and experimentally investigated the perfect optical absorptance of a photonic heterostructure composed of a truncated all-dielectric photonic crystal (PC) and a thick metal film in the visible regions. The three simulated structures could achieve narrow-band perfect optical absorption at wavelengths of 500 nm, 600 nm, and 700 nm, respectively. Based on the measured experimental results, the three experimental structures achieved over 90% absorption at wavelengths of 489 nm, 604 nm, and 675 nm, respectively. The experimental results agreed well with the theoretical values. According to electromagnetic field intensity distributions at the absorption wavelengths, the physical mechanism of perfect absorption was derived from the optical Tamm state (OTS). The structure was simple, and the absorption characteristics were not significantly affected by the thickness of the thick metal layer, which creates convenience in the preparation of the structure. In general, the proposed perfect absorbers have exciting prospects in solar energy, optical sensor technology, and other related fields.
