Terahertz chemical physics analysis of kerosene adulteration using a high-precision photonic crystal fiber

This paper presents a high-precision terahertz chemical physics investigation of kerosene adulteration in fuels through electromagnetic modeling of a photonic crystal fiber (PCF) system. The sensor's performance was quantitatively examined in the frequency range of 1.00 to 3.00 THz. Kerosene was poured into the fiber's center core, and the effects were examined by varying the strut size. The performance of this detector was tested at THz frequencies; at 2.2 THz, the PCF sensor showed values relative sensitivity (RS) of about 97.05%, the effective material loss (EML) of 0.00658 cm -1 , and the confinement loss (CL) of 8 × 10 ⁻10 dB/m. The suggested optical sensor has the potential for detecting kerosene adulteration because of its great sensitivity and remarkable precision. This invention would make it possible to guarantee that customers obtain pure, premium petroleum fuel free of kerosene contamination.
