MXene-Based Perfect Absorber Design and Refractive Index Sensing Performance
In this study, a MXene-based electromagnetic absorber with a simple design at terahertz frequencies is proposed. An absorber that has a MXene layer drilled into with square and circular cavities and a thin aluminum layer as a reflector was examined. With the proper design of the structure dimensions, a MXene-based refractive index sensor with a dual-band at THz frequency and \(99.93\%\) and \(97.85\%\) absorption levels were obtained. The proposed design achieved 1983 and 1935 Q-factor values at frequencies of 0.446 THz and 0.583 THz, respectively. The proposed sensor with fractional bandwidth of \(0.050\%\) and \(0.052\%\) has sensitivity values of 686.2 and 557.6 (GHz/RIU). The figure of merit of the proposed sensor is calculated as 3049.8 and 1852.5 (1/RIU), and the proposed sensor is compared with sensor available in the literature. Since the designed absorber can detect refractive index changes, it also has potential applications in the identification of biological samples.
期刊介绍：
Plasmonics is an international forum for the publication of peer-reviewed leading-edge original articles that both advance and report our knowledge base and practice of the interactions of free-metal electrons, Plasmons.
Topics covered include notable advances in the theory, Physics, and applications of surface plasmons in metals, to the rapidly emerging areas of nanotechnology, biophotonics, sensing, biochemistry and medicine. Topics, including the theory, synthesis and optical properties of noble metal nanostructures, patterned surfaces or materials, continuous or grated surfaces, devices, or wires for their multifarious applications are particularly welcome. Typical applications might include but are not limited to, surface enhanced spectroscopic properties, such as Raman scattering or fluorescence, as well developments in techniques such as surface plasmon resonance and near-field scanning optical microscopy.
