“…Similar trend curves of TM-reflectance pronounced with a narrowest FWHM were already obtained by the use of nanostructured gold film [38], and a multiple-multilayered structure [11]. Generally, the subject on the investigation of SPR sensors in view to develop significant applications, in preferential conditions by the use of thin metallic layers with optimal thickness, has already been considered by several research groups [35,38,39]. To complete the above theoretical analysis, the impact of larger LHM thickness compared to the wavelength,  on TM-reflectance is, next considered in the range of 0.1m to 100m.…”

“…For the study of such a structure optical response wavelength,  of the incident TM-polarized beam is fixed. Let us recall that the numerical method (TMM) is generally valuable to simulate optical properties determined on absorption (A)/reflectance (R) and transmittance (T) spectra [33], which obey to the relationship: A+R+T=1, emitted from Nmultilayer arrangements [2,34,35,36].…”

“…The fundamental property that characterizes the most nanostructured materials based SPR sensors, is the angular or spectral sensitivities to changes in RI of a tested medium in direct contact with the active material layer involved. Otherwise, shift implied from the change of sample RI in the resonance condition observable on the light reflected from a coupling configuration, has been evaluated in different dependencies [34,35,47,48]. Starting from the above selective conditions in terms of minimums of width and reflectance dip depth, let us identify separately the effect that implies the thickness, dD of the intermediate layer.…”

This work addresses a theoretical analysis on optical planar surface plasmon resonance (SPR) sensors. The proposed plasmonic system consists of an active left-handed material (LHM) stacked between a glass-prism and a sensing environment. To evaluate the limits of the surface sensitivity related to SPR excitation, two arrangements between previous media are separately investigated for comparison. Employing the transfer matrix method (TMM), angular TM-reflectance calculations and intrinsic sensing characteristics of previous arrangements, have been investigated with the impact of thicknesses and refractive index (RI) of the media involved. We found the suitable prism material RI, and the preferential arrangement between LHM and sensing environment allowing, thus the increase of the detection sensitivity of SPR excitation. The results of TM-reflectance obtained by varying the sensing environment RI, indicate the ability of the configuration to support an surface plasmon (SP) mode, with a tunable Q-factor from 72 to 748. In addition, distinct optical functionalities achieved with the proposed mono-layer LHM system exhibiting a single SPR mode, and multiple resonant oscillations, are highlighted on both the effects of RI and structure ‘thicknesses. Finally, the relationships between characteristics of TM-reflectance spectra versus the performance parameters are analytically derived.

“…The key advantage of the SPR sensor is user friendly, offers many other advantages such as easy use, reliable and fast response. From the last decade, many works have been carried out to improve the performance of the SPR sensor [17][18]. Kretschmann.s configuration is commonly used in SPR sensing because in this configuration, a thin layer of silver or gold metal is coated on the glass substrate after that a film is depositedon the metal surface that is sensitive for targeted chemical.…”

The tropospheric aerosol characterization is important for understanding environmental process as well as human health safety. In this study, the surface plasmon resonance sensor is proposed for the detection of ammonium sulfate which is an important component of aerosols. The reflectivity of proposed sensor waveguides is calculated as a function of the incident angle using the transfer matrix method. The performance of proposed sensors having sol-gel film of tetraethylorthosilane and thymolblue are studied and compared. Firstly, the dispersion characteristics are obtained for different modes, and it is observed that the modes are tightly bound in thymol blue waveguide in comparison to tetraethylorthosilane waveguide. Further, the magnetic field distributions are also studied and compared for proposed waveguide sensor configurations. It is found that the sol-gel film of thymol blue waveguide provides high sensitivity while tetraethylorthosilane waveguide shows high figure of merit. Keywords: aerosol, surface plasmon resonance sensor, reflectivity, sensitivity, detection accuracy.
