摘要

本文分析了一种极化不敏感磁可调谐完美超材料吸收体,并展示了它作为折射率传感器的功能。所述吸收体的单元胞结构由铝接平面上的十字形砷化铟(InAs)阵列组成,尺寸小于[公式:见文],厚度为7.5[公式:见文][公式:见文],周期为9[公式:见文][公式:见文],使其成为超薄吸收体。所提出的吸收体在0.4的磁场(B)下提供99.99%的平均吸收[公式:见文]。共振频率和相应的吸收率可以通过改变磁场[公式:见文]-0.4[公式:见文]T来控制,这提供了高吸收率,同时频谱偏移0.3[公式:见文]THz/T。此外,还进行了参数分析,确定了结构设计参数的最优值。此外,仿真结果表明,所提出的结构对周围的RI值变化非常敏感,因此,所提出的结构可以作为一个灵敏度高达1.083的RI传感器[公式:见文]太赫兹/RIU在1-1.6[公式:见文]RI范围内。此外,结果表明,该传感器可以检测乙醇、汽油、石蜡、氯化钠、二硫化碳等不同的化合物,平均灵敏度为0.925 THz/RIU。因此,所提出的吸收剂具有获得的灵敏度,可以用作生化传感器,使其成为化学工业中诊断不同危险化学品的最佳竞争者之一,并在生物医学用途中找到其适用性。

Polarization-insensitive magnetically tunable perfect absorber for refractive index sensing applications
In this paper, a polarization-insensitive magnetic tunable perfect metamaterial absorber is analyzed which shows its functionality as a refractive index (RI) sensor. The unit cell structure of reported absorber consists of a cross-shaped Indium Arsenide (InAs) array over aluminum ground plane and has dimensions less than [Formula: see text] with thickness of 7.5[Formula: see text][Formula: see text] and periodicity of 9[Formula: see text][Formula: see text] making it an ultra-thin absorber. The proposed absorber provides an average absorption of 99.99% on the implementation of magnetic field (B) at 0.4[Formula: see text]T. The resonance frequency and corresponding absorption rates can be controlled by varying the magnetic field from [Formula: see text]–0.4[Formula: see text]T which provides high absorption as well as shift in the frequency spectrum by 0.3[Formula: see text]THz/T. Additionally, parametric analysis has also been done to confirm the selection of the optimum value of the designed parameters of the structure. Furthermore, simulation results reveal that the proposed structure is very sensitive to the change of RI values in the surroundings thus, the proposed structure can be employed as a RI sensor high sensitivity of 1.083[Formula: see text]THz/RIU over the range of 1–1.6[Formula: see text]RI. In addition, the result shows that the sensor can detect different chemical compounds such as ethanol, gasoline, paraffin, sodium chloride, carbon disulfide with an average sensitivity of 0.925[Formula: see text]THz/RIU. Thus, the proposed absorber with obtained sensitivity can be utilized as a biochemical sensor, making it one of the best contenders for chemical industry uses in diagnosis of different hazardous chemicals as well as finding its applicability in biomedical uses.

期刊介绍: Launched in 1987, the International Journal of Modern Physics B covers the most important aspects and the latest developments in Condensed Matter Physics, Statistical Physics, as well as Atomic, Molecular and Optical Physics. A strong emphasis is placed on topics of current interest, such as cold atoms and molecules, new topological materials and phases, and novel low dimensional materials. One unique feature of this journal is its review section which contains articles with permanent research value besides the state-of-the-art research work in the relevant subject areas.
