In this article, a graphene metasurface capable of achieving 4-bit encoding is proposed, which can be applied for the detection of cyanides and has multifunctionality as a sensor or an encoder. This device shows promising potential in anti-counterfeiting, information encryption, and related fields.
In this article, we have proposed graphene metasurfaces capable of achieving an encoding of 4 bits. A graphene metasurface placed over a glass substrate is presented. The proposed graphene metasurface can also be applied for the detection of sodium cyanide (NaCN), potassium cyanide (KCN), and hydrogen cyanide (HCN). The detection capacity of all three graphene metasurface sensor (GMSS) structures has been investigated and the structure with higher functionality has been identified. In addition, the device as a sensor has been investigated based on several parameters, and it has been observed that the proposed device generates comparatively higher results. The proposed device has multifunctionality and can be employed either as a sensor or as an encoder. We claim that this is the first graphene metasurface inspired 4-bit encoding device as per the best of our knowledge and can be employed in various applications. The anti-counterfeiting, dynamic information encryption, information authentication, optical data storage, and other related fields stand to benefit greatly from the proposed tunable GMSS and its information encryption and anticounterfeiting applications.
