In this study, we presented a simple highly sensitive sensor based on commercially available solid core photonic crystal fiber (PCF) and surface plasmon resonance (SPR) for measuring the refractive index (RI) of analytes. The numerical simulation finite element method (FEM) has been examined to compute optical properties such as confinement loss, power spectrum, transmission intensity sensor. most inert plasmonic materials (gold silver) have assumed be coated inside with range analytes RI from 1.32 1.40. performance proposed evaluated by tracing several features like wavelength sensitivity, amplitude resolution sensor, figure merit. As result, comparative study between silver gold elements carried out in which maximum sensitivity received 1.15 μm/RIU 1.10 respectively. Whereas, base spectrum obtained was 513 layer. Moreover, effect other structural parameters (air holes layers thickness) sensing taken into an account. According analysis results, would great potential various applications biomedical liquid index.
