Terahertz detection of chemicals through zeonex fiber material

A PCF sensor is proposed for chemical (e.g., glycerol, acetic acid, and water) sensing through Zeonex fiber material. We investigate relative sensitivity, effective are, effective material loss, and confinement loss to analyze the sensor performance. The proposed sensor offers the relative sensitivity of almost 97.7% for glycerol, 96.25% for acetic acid, 95.28% for water at frequency 3.5 THz. In addition, the sensor possesses small effective material loss and tiny confinement loss that are important characteristics of an efficient chemical sensor. Furthermore, the modern fabrication techniques are well fitting for the fabrication of the presented sensor.
