Abstract
This work proposes and statistically analyzes a hexagonal-shaped hollow-core photonic crystal fiber-based edible oil sensor in the terahertz (THz) range. The suggested sensor’s performance was assessed by means of Comsol Multiphysics, a finite element method-based commercial tool. The simulation results demonstrate that the suggested sensor has more than 99% relative sensitivity for different types of edible oils at 1.6 THz under ideal geometric conditions. Furthermore, the suggested sensor exhibits low confinement loss, high numerical aperture and effective area at optimal geometry and operational conditions. The proposed sensor is realizable using conventional production procedures and its superior sensing qualities may make it a key component of real-world oil detection systems.
