Formulating different RI sensors with gold and silver material

Abstract

Plasmonic sensors are gaining in popularity as a research topic due to their potential to overcome a number of electronic device flaws. Surface Plasmon Polaritons (SPPs) are a promising choice for producing highly accurate biosensors due to their unique optoelectronic characteristics that exceed the diffraction limit at a nanometer scale. Plasmonic refractive index sensors based on MIM waveguides are gaining popularity for their molecular binding and instant label-free detection. We attempted to develop a plasmonic sensor for the refractive index that had a high degree of sensitivity and optical features that could be tuned. The initial attempted designs along with their performance has been discussed as well. An elaborate physical mechanism of the observed sensor performance i.e. energy streamlines, transmittance spectrum, surface power flow intensity, magnetic and electric field distributions, and sensor performance has been shown here. We also tried to entail how the variation of different parameters has an effect on the performance matrices. Lastly we showcased our future plans and endeavors regarding the design of the plasmonic sensor
