Plasmonic nano-antenna application to chemical gas sensor

In this paper, we would like to demonstrate the use of graphene covered plasmonic antennas for chemical gas sensing applications. Simulation for the plasmonic dipole nanoantenna was performed using the Finite Difference Time Domain (FDTD) tool by Lumerical Inc. The simulation for the dipole nano antennas were verified with the experimental results. The bulk sensitivity for the dipole nanoantenna is also analyzed. Results are included to show the working device.
