چکیده
The present manuscript describes the theoretical understanding of nanoporous alumina based fiber optic sensing structures. Cavity Maxwell Garnett theory is used to calculate dielectric functions proposed layer. performance structure evaluated in terms its sensitivity towards change refractive index nearby medium. sharpness resonance has also been calculated as an estimation parameters. It observed that approximately 13 times more sensitive than conventional sensors. study further extended by replacing nanolayer aluminum with gold. A comparative provided efficiency probe. effects pore radius, thickness adsorbed medium and shell radius have studied.

Performance Evaluation of a Bilayer SPR-Based Fiber Optic RI Sensor With TiO2 Using FDTD Solutions
We proposed a new bilayer surface plasmon resonance-based fiber-optic refractive index sensor with silver and an over-layer of TiO2. We numerically investigated the optimal thickness of TiO2 over-layer in the proposed sensor and compared its performance to that based on typical bimetallic layers of silver-and-gold in the aqueous media using finite-difference time domain approach. We show that t...

Fiber optic sensors can be used to monitor deformation and/or the overall integrity of structure components. In this paper, we propose a fuzzy control theory based control principle for sensors, and design a new kind of fiber optic sensor used for Geological monitoring. In order to validate the efficiency of the designed sensor, we simulate a water inrush model in a coal mine, and observe the w...
