Fano Resonant Gas Sensors
One of the most important global issues as classified by the United Nations is related to health. And one way to help mitigating this concern consists in developing precise and low cost sensors for toxic gas to avoid contamination and help in saving human lives. In this vein, the demand of the gas sensors is increasing in the fields of environmental monitoring, oil and gas, automotive, building safety, and also in the house hold consumer market. A fresh approach is therefore imminent to design low cost, efficient and sensitive gas detection systems. In this internship, we propose a new class of the nano-particle impregnated integrated gas sensors based on the microwave Fano resonances. In fact, greenhouse gases have refractive indexes values close to that of the air which makes them very difficult to differentiate. Hence, the Fano-resonance, which is known for its high sensitivity, can be exploited to resolve the properties of these gases. Moreover, when the Fano-resonance occurs in the presence of nanomaterials, its sensitivity is much enhanced leading to ultra-sensitive gas sensors. The proposed sensors are targeted to detect and measure the concentration of the H2S, NOx, SOx and CO2 gases, commonly found in the oil wells.
