Abstract

This work aims to introduce a gas detection structure based on stacked layers of graphene-spacer-metal. The presented structure consists of three stacked layers. The first layer is the periodic arrays of graphene disks on top of a typical dielectric such as TOPAS or KAPTON with a known refractive index. Then the second layer provides an air gap opening room for a sample environment. Finally, the third layer includes the dielectric and a continuous graphene sheet. All the exploited elements are modeled by circuit element while the equivalent impedance of the whole structure is calculated. The impedance matching concept is also exploited to obtain absorption power based on the calculated impedance. Additionally, full-wave simulation is performed to investigate the circuit modeling accuracy. Achieving a perfect match for absorption versus frequency verifies the developed method's robustness. Furthermore, comprehensive and ample simulation results are reported to highlight the sensitivity and reliability of the proposed gas detector.

这项工作旨在介绍一种基于石墨烯-垫片-金属堆叠层的气体检测结构。所介绍的结构由三层堆叠层组成。第一层是在具有已知折射率的典型电介质（如 TOPAS 或 KAPTON）上的石墨烯圆盘周期性阵列。然后，第二层为样品环境提供气隙空间。最后，第三层包括电介质和连续的石墨烯薄片。所有利用的元素都以电路元素建模，同时计算整个结构的等效阻抗。还利用阻抗匹配概念，根据计算出的阻抗获得吸收功率。此外，还进行了全波仿真，以研究电路建模的准确性。吸收功率与频率的完美匹配验证了所开发方法的稳健性。此外，还报告了全面而充分的仿真结果，以突出所提议气体探测器的灵敏度和可靠性。
