Stepped graphene-covered plasmonic dipole antenna for detecting \(\text {NO}_2\) gas at mid-infrared frequencies
In this paper, a graphene-based plasmonic antenna is presented to operate as a gas senor based on chemical doping. The proposed structure has a periodic geometry. The principle design is based on manipulating the dipole plasmonic antenna geometry to enhance the electric field in the gap of the antenna as a small change of graphene Fermi energy because of the molecules adsorption results in a significant shift of the resonance wavelength of the diffraction spectrum. The results demonstrate that the proposed sensor enables the detection of \(\text {NO}_2\) gas by around 1160 molecules with steps of 15.07 nm of the resonance wavelength shifts in the transmission spectrum. It is believed that this sensing structure could open a new window to realize a variety of graphene-based photonic sensors, for potential applications in the fields of biology, medicine, and chemistry.
期刊介绍：
he Journal of Computational Electronics brings together research on all aspects of modeling and simulation of modern electronics. This includes optical, electronic, mechanical, and quantum mechanical aspects, as well as research on the underlying mathematical algorithms and computational details. The related areas of energy conversion/storage and of molecular and biological systems, in which the thrust is on the charge transport, electronic, mechanical, and optical properties, are also covered.
In particular, we encourage manuscripts dealing with device simulation; with optical and optoelectronic systems and photonics; with energy storage (e.g. batteries, fuel cells) and harvesting (e.g. photovoltaic), with simulation of circuits, VLSI layout, logic and architecture (based on, for example, CMOS devices, quantum-cellular automata, QBITs, or single-electron transistors); with electromagnetic simulations (such as microwave electronics and components); or with molecular and biological systems. However, in all these cases, the submitted manuscripts should explicitly address the electronic properties of the relevant systems, materials, or devices and/or present novel contributions to the physical models, computational strategies, or numerical algorithms.
