Abstract
AbstractA systematic investigation of the performance of CaF2‐Ag‐BaTiO3 heterostructure based SPR sensor has been performed. The article focuses on the point that a suitable dielectric layer and precise optimization process can lead to high performance. E‐coli bacterial is considered as analyte medium. The sensor design is optimized by simultaneous varying the thickness of Ag (dM) and BaTiO3 (dA) at wavelength (λ) = 1000 nm which provided an optimized figure of merit (FOM) of 4510 RIU−1 at dM = 48.1 and dA = 3.2 nm. Further, FOM is again enhanced by simultaneous optimization of wavelength and thickness of BaTiO3 which provided an FOM of 9108 RIU−1 at λ = 992 and dA = 3.3 nm at fixed dM = 48.1 nm. This is designated as final optimum radiation damping (ORD) condition for the proposed sensor design. The power loss curve and normalized electric field are plotted at ORD condition leads to the FWHM of 0.0200° and sensitivity of 182.17 deg. RIU−1 with power loss ratio of 2.59 and field enhancement factor of 1.06. The combined performance factor (CPF) at optimized parameters is 24276.79 µm4/RIU which enables the realization of sensor more practically.
