Designing high sensitivity surface plasmon resonance sensor using a left-handed material layer

In this contribution, we propose a new plasmonic configuration that can be functionalized in two wavelength regimes to generate single interface mode or multiple modes. The structure comprises negative metamaterial Left-Handed Material (LHM) coated on 2S2G-glass prism and adjacent with sensing medium. According the results, thickness affects significantly potential of operate as conventional structured formed by Fabry-Perot cavities. Additionally, we, also show used refractive index sensor defined range 1 1.53 unit (RIU) where full width at half maximum (FWHM) SPR curve characteristic’s manipulation such FWHM p-reflectivity decreases for thick LHM layer. To understand obtained optical response from proposed waveguide was numerically predicted use transfer matrix method (TMM) Fresnel’s theory. addition, potentials designed an modulator interferometer are presented.
