The graphene-based absorbers are widely applicable and highly efficient. Graphene has very high electrochemical properties due to which tuning characteristics can be achieved with efficient and broadband absorption response. For this review paper, we have divided the graphene-based absorbers into three categories (Absorber sensors, Solar absorbers, and THz absorbers) based on their applications. We have presented a detailed discussion on various designs and their analysis in this paper. Absorber sensors are mainly applicable in biosensors for the detection of hemoglobin, urine biomolecules using the tuning properties of graphene, and are also applicable in medical, environmental, chemical, biological diagnostic applications. Solar absorbers are applicable in energy harvesting devices. Adding graphene layer in solar absorber design gives the highly efficient and broadband absorption response. THz absorbers are applicable in the THz applications in sensing and imaging devices. Some of the THz absorbers are improving the applications in the new field of nano-optics with 2D material. Graphene and its excellent electrical and optical properties are applied in material designs which create new structures applicable in novel applications like sensing, imaging, solar energy harvesting, etc.This is an Open Access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium provided the original work is properly cited.

Encryption is a very essential part to secure data communication in today's world where there is a threat of stealing data. We have proposed a graphene-based metasurface biosensor for sensing and encryption applications. The biosensor is designed to sense the hemoglobin (HT) biomolecules with high sensitivity. The results are analyzed in the form of transmittance and electric field of the proposed graphenebased metasurface biosensor. The graphene layer's chemical potential is varied to achieve the coding of '0' and '1'. This creates one-digit coding. The array of this proposed structure with this coding can be used for encryption applications. The biosensor design is analyzed for four HT concentrations and their sensitivity is compared. Different geometrical parameters are analyzed and their effect is observed for tunability. The response from the design can be useful in future biomedical and data encryption applications.

“…In 1996, Pendry et al proposed the first artificial metamaterial composed of periodic structures which could achieve negative dielectric constant and negative permeability [ 1 , 2 ]. Based on the negative property, the wave can be manipulated and the metamaterials have important applications in infrared imaging [ 3 ], focus second-harmonic beams [ 4 ], meta-holograms [ 5 ], cloak [ 6 ], absorbers [ 7 ], and so on. Analogous to electromagnetic metamaterials, in 2000, Liu et al presented the first artificial acoustic local resonance-type metamaterial which can achieve negative effective mass densities at a fixed frequency of 400 Hz [ 8 , 9 ].…”

This work proposes a method for actively constructing acoustic metasurface (AMS) based on the split hollow cuboid (SHC) structure of local resonance, with the designed AMS flexibly manipulating the direction of reflected acoustic waves at a given frequency range. The AMS was obtained by precisely adjusting any one or two types of structural parameters of the SHC unit, which included the diameter of the split hole, the length, width, height, and shell thickness of the SHC. The simulation results showed that the AMS can flexibly manipulate the direction of the reflected acoustic waves, and the anomalous reflection angle obeys the generalized Snell’s law. Furthermore, among the five structural parameters, the AMS’s response frequency band is widest with the hole diameter and height, followed by the length and width, and narrowest with the shell thickness. It is worth noting that comprehensive manipulation of two parameters not only broadens the response frequency band, but also strengthens the effect of the anomalous reflection at the same response frequency. The subwavelength size of the AMS constructed with such a comprehensive method has the advantages of a small size, wide response band, simple preparation, and flexible modulation, and can be widely used in various fields, such as medical imaging and underwater stealth.
