Efficient way for chemicals identification using hexagonal fiber with the terahertz (THz) band

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