Plasmonic nanostructured chips for chemical and biological sensing in the UV-regime

摘要

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