We propose plasmonic nanogratings such that they have tunable plasmon resonances in far- and deep-UV wavelength ranges. These plasmonic nanostructures and nanogratings of different plasmonic materials have been simulated using Finite Difference Time Domain modeling and the Rigorous Coupled Wave Analysis. Application of these plasmonic nanostructures for surface plasmon resonance and localized surface plasmon resonance based sensing in the UV wavelength regime has been demonstrated by calculating the shifts in the plasmon resonance wavelength for changes in either the bulk refractive index or the localized refractive index of the medium next to the plasmonic structures.
