Identification of Cyanide within Hollow Core Photonics Crystal Fiber

Abstract

Nerve Cyanide is very dangerous especially for human body and for this reason, perfect extent identification of cyanide is very worthy. In this research, PCF based cyanide sensor is illustrated where, sodium cyanide (NaCN) and potassium cyanide (KCN) are taken as analyte. COMSOL Multiphysics is conducted for the simulation of recommended model. The recommended model exhibits 88.5% sensitivity while NaCN is chosen as analyte at frequency 1.3 THz. This model has very insignificant effective material loss (EML) and only 0.0050 cm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-1</sup> EML is noticed while KCN is chosen as analyte. Moreover, this recommended model has very negligible confinement loss (1.2×10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-13</sup> dB/cm).
