This work presents a "refractive index" sensor based on "photonic crystal fiber" and "surface plasmon resonance" phenomenon. A combination of Gold (Au) with Titanium Nitride (TiN) is used as a metallic layer in the presented sensor design. Water and transformer oil having RI1.330 and RI1.340 are analyzed through a developed spectroscopy setup which lays the condition for the RI sensor designing. A new relationship between transmission (%), absorbance (AU), and refractive index (RI) is developed and presented in this article. The sensor analysis is performed using the "finite element method" and "perfectly matched layer" conditions. The proposed sensor has obtained a "wavelength sensitivity (WS) " of 10000nm/RIU and 11000nm/RIU correspondings to TM mode and TE mode, respectively. A high "amplitude sensitivity (AS)" of 11280RIU(-1) and 7550RIU(-1) is obtained for TM mode and TE mode, respectively. The "sensor resolution (SR) " of 1.00 x 10(-5)RIU and 9.09 x 10(-6)RIU are reported for TM mode and TE mode, respectively. High linear fitting between resonance wavelength and RI, "full-wave half maximum (FWHM)" and "figure of merit (FOM)" are also reported for the proposed sensor. The peak values of the sensing parameters are obtained for RI1.330 and RI1.340, corresponding to the TM mode and TE mode, respectively.
