Description
Summary:The dodecagonal hollow core PCF-based edible oil sensor is put forward in this paper and quantitatively investigated over the terahertz regime. A professional tool based on the finite element method (FEM) called COMSOL Multiphysics is used to evaluate the proposed sensor's performance. The simulation findings show that the proposed sensor outperformed previous studies with high sensitivity of 102.07% and an incredibly low total loss of 4.35 × 10 - 4 cm - 1 at 3.2 THz with the optimum geometric parameters. In addition, this sensor has a high numerical aperture of 0.43 with ultra-low confinement loss of 4.92 × 10 - 15 dB/m . The huge hexagonal-shaped cladding uses to simplify its fabrication. Soon, everyday life oil detection technologies will heavily rely on its exceptional sensitivity and directing abilities.
