The design and requirement of corrosion-resisting nanocarbon nanocomposites have been investigated for chopping-edge aerospace purposes. Determined by the special properties of optical Fano resonance and plasmonic-waveguide coupling devices, this paper explores a novel refractive index focus sensor framework. The sensor structure is made up of a steel–insulator–metal (MIM) waveguide and https://www.directivepublications.org/journal-of-applied-nanoscience/
