摘要

本文介绍了一种用于气体传感的石墨烯新月形偶极子等离子体天线。该气体传感器在900 ~ 1600 nm波长范围内具有可重构的吸收特性。研究了传感器尺寸对不同气体总吸收率的影响。石墨烯单层用于增强气体分子在其无偏态下的吸收。当n=1.4时，总吸收截面(ACS)值的增强值对于未加载的石墨烯传感器为1.028×105 nm2，对于加载石墨烯的情况为1.77×105for nm2。该传感器的灵敏度为677.5 nm/RIU。利用等离子体新月形偶极子天线的传感器阵列增强了气体吸收。6×6偶极子阵列的总ACS峰值为5.38×106nm2。

Reconfigurable Graphene Gas Sensor using Plasmonic Crescent Dipole Antenna

In This paper, graphene crescent dipole plasmonic antenna is introduced for gas sensing. The proposed gas sensor has reconfigurable absorption characteristics in the wavelength range from 900 nm to 1600 nm. The effect of the sensor dimensions on the total absorption of different gases is investigated. A graphene monolayer is used to enhance the gas molecules absorption in its unbiased state. An enhancement of the total absorption cross-section (ACS) values for $n=1.4$ is 1.028×105 nm2 for unloaded graphene sensor, and is 1.77×105for graphene loaded case. The proposed gas sensor has sensitivity of 677.5 nm/RIU. An enhancement of gas absorption is achieved by using a sensor array of the plasmonic crescent dipole antenna. The total ACS peak value is 5.38×106nm2 for 6×6 dipole array.
