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.
