In this paper, a terahertz range hybrid structured with square hollow-core PCF-based edible oil sensor is presented and statistically examined. For the purpose of determining this proposed hollow core fiber's propagation characteristics, the finite element method is used with a circular perfectly matched layer boundary condition. In ideal geometrical circumstances, the recommended detector exhibits 98.45% relative sensitivity to various edible oils at optimum frequency of 1.8 THz. An extensive simulation of that microstructure fiber across THz frequency range reveals that it is possible to concurrently achieve very low effective material loss of 0.004632 cm−1 and a very low confinement loss of 1.07 × 10–15 dB/m. In addition, the proposed fiber is thoroughly studied for other crucial factors like total loss, spot size, and numerical aperture. This optical waveguide's outstanding achievements will make it possible to use it in a variety of practical terahertz applications. [ABSTRACT FROM AUTHOR]
