“…Previously many researchers found much better optical properties using photonic crystal fibers (PCF) of different structures. For statable, using circular cladding with elliptical core-based PCF structure S. Asaduzzaman et al The loss of confining and relatively sensitive capacity was 40% [10] and 41% confinement loss and relative sensitivity were achieved with the application of PC-PCF fiber, M Arif et al [11]. Ahmed achieved relative sensitivity and a higher containing loss of 57 percent by the use of octagonal PCF [12].…”

This research article demonstrates a good simulation result for identifying and detecting various industrial chemicals in a Terahertz (THz) waveguide with a new heptagonal, five layers of heptagonal photonic fiber elliptic form, heptagonal clading shape (H-PCF). COMSOL 4.2 software based on finite element (FEM) methods and perfectly matched layers check our composition (PML). The different chemicals are also differentiated and identified by each other in different parameters H-PCF fibers show a high relative sensitivity of ethanol of approximately 86.50 percent after numerical analysis, Benzene around 89.35%, and water around 85.15% at a frequency of around 0.7 THz. In our experiment, we obtained very low confinement losses at 1 terahertz (THz) such as 5.95×10−08 dB/m for Ethanol 6.67×10−08 dB/m for Benzene, and 5.80×10−08 dB/m for water. Regarding these results, we can strongly recommend that our proposed heptagonal photonic crystal fiber (H-PCF) will be more congenial in biomedical, bio-medicine, and industrial areas for the identification and detection of various types of chemicals with the help of a THz waveguide.

To detect chemicals, we proposed a photonic crystal ber (PCF) with hexagonal cladding and a hexahedron core (THz). Circular air holes (CAHs) in the vestibule provide the basis of the suggested sensor. To develop and evaluate our suggested hexahedron PCF sensor, we employed the nite element (FEM) technique and perfectly matched layers (PML), which utilized the optical parameters numerically.Here, 92.65%, 95.25%, and 90.70% are relatively sensitive, and con ning losses are low. the value 5.40×10 − 08 , 6.70×10 − 08 dB/m, and 5.75×10 − 08 dB/m for three chemicals such as Ethanol (n = 1.354), Benzene (n = 1.366) and Water (n = 1.330) and effective material loss (EML) of 0.00694 cm − 1 . The suggested Hx-PCF sensor has been successfully tested at 1 THz. We are certain that the suggested sensor's optimal geometric structure can be manufactured and that it can contribute to real-world applications in biomedicine and industry. In terahertz areas, our suggested PCF ber is also suited for a wide range of medical signals and applications (THz).
