This work proposes a Hexagonal-core Photonic Crystal Fiber (H-PCF) based edible oil sensor in the Terahertz (THz) range (1.0 THz ≤ f ≤ 3.0 THz) and different sensing characteristics are numerically analyzed. The suggested sensor’s performance was assessed by means of COMSOL multi physics, a commercial program that uses the Full Vector Finite Element Method (FV-FEM). The computational results indicate that the relative sensitivity is 85.591%, 84.648%, 82.625%, 82.683%, and 79.161%, respectively, at f=2.2 THz, for several types of sunflower oil, mustard oil, coconut oil, olive oil and palm oil; and the corresponding effective areas are 7.22 × 10-8 m2, 7.09 × 10-8 m2, 6.83 × 10-8 m2, 7.09 × 10-8 m2, 6.5231 × 10-8 m2.
